Varun Saxena commented on YARN-5561:
A small nit again in javadoc. Sorry for nitpicking.
"Return a set of containers belongs to given application attempt id" should be
"Return a set of container entities belonging to given application attempt id"
Other than that +1 from my side too.

Varun Saxena commented on YARN-5561:
Few nits.
# "Return a set of application-attempts entities" should be "Return a set of
application-attempt entities" in javadoc
# Return a single application-attempt entity of the given Id => Return a single
application-attempt entity for the given attempt Id in javadoc
# Return a set of containers entities belongs to given application attempt =>
Return a set of container entities belonging to given application attempt in
javadoc
# Above getContainer method javadoc says " Return a single application-attempt
entity of the given Id" which is incorrect.

[~rohithsharma], could you kindly update v.03 of the patch to address several
checkstyle issues (the ones other than the number of arguments violations)?
Then we can go ahead with this. Thanks!

That should be fine. We can keep a JIRA open till next drop on trunk and update
documentation via it just like we did before first drop on trunk. There can be
multiple contributors to the JIRA.

I would prefer to take it up as separate JIRA as consolidated documentation
update. And also I suspect and pretty sure, there are couple of more changes
will come which require to modify documentations.

Varun Saxena commented on YARN-5561:
[~rohithsharma], should we update documentation for this ?
We can also do it in a separate JIRA though because some of the query params
seem to be repeated in the documentation. Probably we can consolidate these
query params at a single place in that JIRA and add these endpoints as well. Or
you can add the endpoints here itself. As you wish.

Yeah what I meant is a separate endpoint may be required for things like that.
Not sure what we name it though. Or we can just put everything under the hood
of ws/v2/timeline. Anyways maybe a separate JIRA should be filed for that
disucssion.

During weekly sync up, we had discussion regarding for providing new REST URL
i.e */ws/v2/applicationhistory*. One of the point discussed is what is the
advantage is having separate REST end points which returns is *Report format?
It will become a another version existing data with different format. But ATSv2
TimelineEntity is super set of all where in user might required information
which are not in *Report. So, if required information are published under first
class entity info level like YARN-5699 doing, then it is more than sufficient.
The consensus are
# we publish the yarn entities important information at first class entity
info level so that user can make use of these information to query using
infofilters.
# We will be going ahead with adding new REST end points(patch already attached
i.e YARN-5561.03.patch) which are enhancement of existing getEntities.

Varun Saxena commented on YARN-5561:
I was also thinking that we can have an endpoint like /ws/v2/applicationhistory.
This can be used to not only serve app attempt.container reports but also serve
use cases like serving aggregated logs of historical apps. We would need to
serve aggregated logs from somewhere too. This will be useful for UI as well.
Regarding metrics, well we can always extend ContainerInfo to carry metrics as
well. Right ?

Thanks for clarifications..
Though utility class is very useful for converting reports, one major concern
is number of REST calls to be invoked by user. Especially in Web, this will
become 2 REST calls which decrease the performance.
Basically, me and Li lu was thinking to embedded
TimelineYARNEntityReaderWebService to timelinereader daemon with REST path
*/ws/v2/applicationhistory*. These REST end points would take care of
retrieving entities from storage and convert to required YARN reports such as
ApplicationAttemptReport or ContainerReport etc.
bq. Also, please note that what's contained in the current REST output would
likely to be a superset of *Report;
I agree that current *Report would be subset of TimelineEntity object. So ,
this we can solve by defining new *Report which compatible with ATSv2 either by
extending current *reports since metrics are required. If any new fields
published to ATS, then It is contract between publisher and reader that these
information fields should added in *Report. New *report class is only wrapper
over TimelineRntity object for YARN entities. And at any point of time, if user
thinks he need more informations, he can query from ATSv2 which is always open.

bq. Couple of more doubts just to be in sync, Does translation layer is
with-in-the-reader service or separate ? What is the format of report object?
Is this report object is general or only yarn entities?
I was thinking of something like utility classes that can create and return
specific report types. For example,
{code}
ApplicationAttemptReport getApplicationAttemptReport(TimelineEntity
appAttemptEntity);
ContainerReport getContainerReport(TimelineEntity containerEntity);
{code}
These classes can be (and probably would need to be) in the yarn common module
so any REST client can invoke it to get a translated object back.

bq. Could not get the intention behind pulling it out to a separate daemon
though. Can you elaborate on that ?
bq. could you elaborate more on the concrete use cases for the need of a
separate daemon for now?
I meant say, Initial idea is combine YARN entity reader along with
TimelineReaderWebService. In case folks do not agree then next proposal is to
pulling out as separate daemon. Even I am decline for pulling out from
timelinereader service but if other folks have any concern for combining along
with timelinereader then it is an option.
bq. As we briefly discussed during the call the other day, what we need is a
translation layer that can create a Report object out of the timeline entity.
If we implement such a translation layer, would it satisfy this?
Yes. Couple of more doubts just to be in sync, Does translation layer is
with-in-the-reader service or separate ? What is the format of report object?
Is this report object is general or only yarn entities?

I recognize the pain point you're mentioning in terms of wanting the data in
the form of {{ApplicationAttemptReport}} or {{ContainerReport}}. That said,
adding a new daemon should not be done lightly. I am in the opinion that the
bar above which a new component is added to the system should be high. I'm not
sure if this meets that bar.
Also, please note that what's contained in the current REST output would likely
to be a *superset* of {{*Report}}; in other words, there are things in the
entity API that are not in the {{*Report}}. Things like the uid and the
currently discussed entity id prefix come to mind. So we cannot simply replace
the return type, or things will be crippled.
As we briefly discussed during the call the other day, what we need is a
translation layer that can create a Report object out of the timeline entity.
If we implement such a translation layer, would it satisfy this? That way, the
client gets the full timeline entity information, and it can convert it into a
report object fairly easily without writing much code.

I'm generally OK with option 1, as it's quite consistent with my original
thought (see the comment on Aug. 30). The only thing I would like to mention
here is, we gave up this idea before because we thought when web UI requesting
data, it needs to contact two different endpoints. I'm not sure if with current
web UI use cases this problem is alleviated.
bq. This approach can be modified/enhanced to pulling out of ATSv2 to separate
daemon service OR can be start new service in RM itself with application
history.
I'd incline not to go this far as of now. Sure, architecturally we can keep
this flexibility, but could you elaborate more on the concrete use cases for
the need of a separate daemon for now?

Varun Saxena commented on YARN-5561:
Similar to option 1 in terms of having separate endpoints is what we had in
AHS/ATSv1 too i.e. in the form of AHSWebServices. That will clearly delink
APIs'. What do we name it though ? {{ws/v2/applicationhistory}} ?
We can further add things like serving container logs from this endpoint too.
And this can act as one stop destination for fetching YARN specific history
data.
Could not get the intention behind pulling it out to a separate daemon though.
Can you elaborate on that ?

Rohith Sharma K S commented on YARN-5561:

Thanks [~sjlee0] [~gtCarrera9] [~varun_saxena] for reviewing patch.
On second thought, ultimate goal for YARN-5561 and YARN-5699 is to provide an
easy way for YARN Web UI. It would be much helpful for YARN Web UI and also for
the users who wants query containers/app-attempts from CLI if
app-attempts/containers are in the form of ApplicationAttemptReport and
ContainerReport format.
Basically overall intention is to provide flexible REST API to users with
which they can directly make use from response output rather than allowing them
to parse the ATSv2 REST output.
I think it would be good to take early decision rather than struggling at final
stages which leads to many code changes in dependencies especialy YARN Web UI.
Couple of approaches for providing a facility to convert TimelineEntity objects
to respective YARN reports are
# Launch a new web service i.e TimelineYARNEntityReaderWebServices along with
TimelineReaderWebServices. This service would run as part of TimelienReader
daemon. This new service is just an translator to converting TimelineEntity
object to corresponding YARN reports such as ApplicationAttemptReport or
ContainerReport. And this service would contains new YARN specific entities
which are exposed REST end points in this patch. Note that these REST end
points return type are corresponding reports like AppAttemptsInfo. This
approach can be modified/enhanced to pulling out of ATSv2 to separate daemon
service OR can be start new service in RM itself with application history.
# For existing TimelineReaderWebServices, *change the return type* for newly
added REST end points such as
getAppAttempts/getAppAttempt/getContainers/getContainer with
AppAttemptsInfo/AppAttemptInfo/ContainersInfo/ContainerInfo respectively. Cons
to add in TimelienReader service is it becomes bit combination of ATS+YARN
specific details.
Thoughts.? This will bring down many of the JIRA like YARN-5561 YARN-5699 etc
can be combined and avoided altogether .

I don't have a strong preference on those query parameters either, but I think
adding them is totally fine. The latest patch generally LGTM. [~rohithsharma]
would you like to rebase it to trunk and fix the few "longer than 80 chars"
warnings so that we can commit this? Thanks!

That said, these REST end points are enhancement of getEntitties and getEntity.
So, do not want to change any of the query params associated with app-attempts
and container. In future, we never know what metrics/configs/relationships
would be stored in attempts/containers.
{quote}
Regarding whether to retain things that are not needed for app attempts and so
on, I don't have a strong opinion either way, but I might lean slightly towards
leaving them in. Even with the existing queries for them today, we don't
strongly reject them even if they are specified for app attempts but simply
return empty data, right? Also, leaving them in might be slightly more
future-proof. Again these are not strong preferences.
in terms of documenting, let's just be consistent and add the javadoc. Being
consistent is probably a good thing here. If we decide later that javadoc is
superfluous, we could take them out in bulk.
[~rohithsharma], does this need to go into trunk or can it stay in YARN-5355?
If it is needed on trunk (which is the impression I got), then let's change it
to a top level JIRA and create a patch based on the trunk. Once it is committed
to the trunk, we can cherry-pick it onto YARN-5355 (and its associated branch-2
branch).

Well the intention behind my comment was that we will document these REST
endpoints separately. So for the user its a distinct endpoint. The fact that we
in turn redirect this call to entity table is internal implementation.
And if we indicate that you can apply config filters etc., it may indicate that
we store them for containers, app attempts which we don't. And if there is
something which we don't publish from RM/NM, I thought its pointless to have
filter for it. Your thoughts on the same ?
We currently do not restrict clients to publish even YARN specific entities so
they can potentially publish configs for it but I remember we had a JIRA
related to that i.e. do not allow arbitrary clients to publish YARN entities.
I do not have a very strong opinion on this though. Let us see what others
think.
bq. This is one of point of concern for code readability. May be we can capture
in document, but not in java class file. Thought?
We had initially decided we will add both javadoc and documentation. We however
want to trim down the documentation a bit because some query params are
repeated.
Let us keep it consistent no matter what we do. We can probably add non-javadoc
comments over REST methods so that developer can read them. As such REST
endpoints are already captured in documentation for outside users of ATS. I
remember [~rohithsharma] you had a JIRA for it. Maybe we can handle it there if
the team reaches a consensus on this. [~sjlee0], your opinion on this ?

Rohith Sharma K S commented on YARN-5561:
-
bq We do not store configurations at container and app attempt level. So we can
leave out query params associated with it,
bq. Similarly no metrics are stored at app attempt level. Same goes for
relationships. We can add them when we support them, if not for anything but
just to reduce lines in code and documentation
That said, these REST end points are enhancement of getEntitties and getEntity.
So, do not want to change any of the query params associated with app-attempts
and container. In future, we never know what metrics/configs/relationships
would be stored in attempts/containers. Lets keep it as it, if user query
configs/metrics then he gets result in empty. It indicates , there is no
metrics or configs published.
bq. Javadoc will have to be updated I think otherwise we will get a -1 in QA
report. Yes this will unnecessarily increase code size but then there is no
other way out.
This is one of point of concern for code readability. May be we can capture in
document, but not in java class file. Thought?
bq. Update tests for app attempts too ?
Let me update the tests and will update new patch.

Seems like we're reaching much agreement on the general proposal of this JIRA.
[~rohithsharma] would you please update the patch so that we can move forward
with the rest process? Thanks!

bq. Rohith, I think you're saying you are OK without having that API since we
have a query that returns all apps for a flow
RIght, I am fine with all apps for a flow.

Sorry it took me a while to get to this.
I'm generally fine with the newly proposed REST end points (as they seem to be
more like short-handed API for existing ones).
Regarding the need for listing all apps (in a cluster), I agree with others
that it would be quite problematic. If I read this thread correctly, Rohith, I
think you're saying you are OK without having that API since we have a query
that returns all apps for a flow (and one that returns all flow activities).

As of now /apps cab be dropped since apps can be retrieved using flows. Based
on the use case from UI let us decide the /apps at cluster level.

Thanks [~rohithsharma], the two proposed APIs make the app - attempt -
container APIs more comprehensive. LGTM.
bq. are looking for a complete applications page where all applications which
were running/completed had to be listed.
This is something I'm not sure if we'd like to support on the timeline level.
This information is pretty much available on the RM side via the state store.
Why do we want to encourage an expensive operation on the timeline store for
this data?

bq. are looking for a complete applications page where all applications which
were running/completed had to be listed. For this purpose, I think we need the
api as suggested by Rohith. Being said this, We will also be showing hierarchy
from flows too.
So you plan to have 2 app pages. One from a specific flow run and other a list
of all the apps in a cluster. Right ?
[~rohithsharma], how do you plan to support fetching all apps within a cluster ?
Probably you can adopt the approach I had suggested. Because otherwise it would
lead to full table scan.
bq. New API's required. Thoughts?
We should have them for the sake of completeness.

Thanks [~sunilg] for quick response. I will update patch accordingly.
Along with below API's additionally 2 more API require I think. Thoughts?
{noformat}
2. (cluster - )app - app_attempt - container sequence (6)
- /clusters/{clusterid}/apps/{appid}/appattempts/{appattemptid}/containers
- /clusters/{clusterid}/apps/{appid}/appattempts
- /clusters/{clusterid}/apps/{appid}/
- /apps/{appid}/appattempts/{appattemptid}/containers
- /apps/{appid}/appattempts
- /apps/{appid}/
New API's required. Thoughts?
- /clusters/{clusterid}/apps/{appid}/appattempts/{appattemptid}
-
/clusters/{clusterid}/apps/{appid}/appattempts/{appattemptid}/containers/{contianer-id}

Hi [~rohithsharma]
Yes. We are looking for a complete applications page where all applications
which were running/completed had to be listed. For this purpose, I think we
need the api as suggested by Rohith. Being said this, We will also be showing
hierarchy from flows too. Once end use land on this applications page, various
filters/views could be derived. Hence we could also cover or show details of
flows.

Rohith Sharma K S commented on YARN-5561:
-
In *Li lu*'s REST endpoint list, there is one end point which is missed i.e
listing all the apps for given flow name
*/users/{userid}/flows/{flowname}/apps/*.
bq. And based on use case of Rohith maybe list all apps within a cluster as
well.
This is one of the objective of this JIRA when I reported. But there is another
end point from which apps can be retrieved i.e at flow name, the client can get
all the flows in the cluster and for each flow, client can retrieve the apps
using above specified path. So, let me confirm with Sunil does new UI has such
use case to get all the apps per cluster. If so, I will refresh the patch.

bq. We can follow approach suggested by you as well. I do not have a strong
opinion on either. So I will leave it as it is. Lets see what others think.
Fine with me. Once we have a clear view about the current rest end points and
they're not confusing we're good.
bq. And based on use case of Rohith maybe list all apps within a cluster as
well. However in my personal opinion that may not be necessary.
Nice catch. [~rohithsharma] if you feel we need this endpoint, please feel free
to refresh the patch.
Generally LGTM. I'll wait ~24 hrs and then commit the patch.

Looks fine to me as well.
bq. Do we want to reorganize the code in a way consistent with this list?
Well the current organization is based on what we are retrieving that is all
endpoints for fetching entities are together, for fetching apps are together
and so on.
We can follow approach suggested by you as well. I do not have a strong opinion
on either. So I will leave it as it is. Lets see what others think.
bq. discuss the endpoints that marked as weird
These endpoints were added to get all apps belonging to a flow so we skip the
flow run section. There were use cases to fetch all apps within a flow in case
run id is not known. Refer to [~vrushalic]'s [comment on YARN-3864 |
https://issues.apache.org/jira/browse/YARN-3864?focusedCommentId=14940489=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14940489]
We also plan to list all apps for a user or queue in future as well.
And based on use case of Rohith maybe list all apps within a cluster as well.
However in my personal opinion that may not be necessary. You can check with
New Web UI folks.

Sequence 2 in this list seems to be replacing the majority part of the old AHS
APIs, except for container logs. We may use them as a starting point to support
AHS-like use cases in timeline v2.

OK I revisited the patch and our reader REST APIs. Right now we have 26 (!)
APIs for reader server. I tried to organize them in a way easier to understand:
{code}
0. cluster activity (2)
- /flows/
- /clusters/{clusterid}/flows/
1. (cluster - )user - flow - run - app - entity_type - entity_id sequence
1.1 hierarchical (12)
-
/clusters/{clusterid}/users/{userid}/flows/{flowname}/runs/{flowrunid}/apps/
- /clusters/{clusterid}/users/{userid}/flows/{flowname}/runs/{flowrunid}/
- /clusters/{clusterid}/users/{userid}/flows/{flowname}/runs/
- /users/{userid}/flows/{flowname}/runs/{flowrunid}/apps/
- /users/{userid}/flows/{flowname}/runs/{flowrunid}/
- /users/{userid}/flows/{flowname}/runs/
(user, flow, run information omitted since an application is unique in a
cluster)
- /clusters/{clusterid}/apps/{appid}/entities/{entitytype}/{entityid}/
- /clusters/{clusterid}/apps/{appid}/entities/{entitytype}
- /apps/{appid}/entities/{entitytype}/{entityid}/
- /apps/{appid}/entities/{entitytype}
- /clusters/{clusterid}/users/{userid}/flows/{flowname}/apps/ (looks weird,
jumping levels)
- /users/{userid}/flows/{flowname}/apps/ (looks weird, jumping levels)
1.2 uid (6)
- /flow-uid/{uid}/runs/
- /run-uid/{uid}/
- /run-uid/{uid}/apps
- /app-uid/{uid}/
- /app-uid/{uid}/entities/{entitytype} (entity type looks weird)
- /entity-uid/{uid}/
2. (cluster - )app - app_attempt - container sequence (6)
- /clusters/{clusterid}/apps/{appid}/appattempts/{appattemptid}/containers
- /clusters/{clusterid}/apps/{appid}/appattempts
- /clusters/{clusterid}/apps/{appid}/
- /apps/{appid}/appattempts/{appattemptid}/containers
- /apps/{appid}/appattempts
- /apps/{appid}/
{code}
So the new addition looks fine to me. Do we want to reorganize the code in a
way consistent with this list? Right now the code seems to be a little bit
messy. We can do it in this JIRA, or we can open a new JIRA to reorganize these
APIs and discuss the endpoints that marked as weird? Thanks!

I've got offline discussions with several folks on if we should have concepts
like "app-attempt" and "container". From a designer's perspective, app-attempts
and containers should not be included in timeline APIs, but from YARN users
perspective, requesting app-attempt and container level information seems to be
very natural operations, especially since both concepts are top level concepts
in YARN. So I'm relatively fine with having terms like "containers" and
"app-attempts" exposed in timeline APIs, but we may want to be very careful to
not to give an impression that attempts and containers are on the hierarchical
order as flows and flowruns.
So how about having two different hierarchical orders:
Order 1, native timeline order: cluster, user, flow, flow-run, application,
entity
Order 2, YARN application order: application, app-attempt, container
Once we're not mixing the two orders in APIs, the logic should be clear.
Thoughts?

Separating out YARN specific details is good idea similar to v1. Here is my
vote will be 50-50 for this approach.
In v1, entities were fully separated out from yarn specific details. But in v2,
Apart from the entities, *Query Apps for a Flow* and *Query Apps for a Flow
Run* and other details are in TimelineReaderWebService. These are belongs to
YARN specific details nevertheless of any underlying storage schema. All the
entities are published under application scope which makes decision harder for
devs to adding a new REST YARN specific end points.
>From the user perspective, I want to share you that say for retrieving all
>the apps with flow/flowrun uses path /ws/v2/timeline, but for retrieving
>attempts uses path /ws/v2/applicationhistory would lead to big question for
>users why there are 2 different Path for same application details!!!.
May be we can takes other folks thoughts too on this.

OK let me clarify: IMO the reader API of YARN timeline service should focus on
serving timeline entities according to caller's request, but not on how to
serve YARN specific use cases. To the storage layer of timeline service,
requesting "container info" should be similar to requesting distributed shell
application information or Tez job information. I noticed that in this patch,
we're passing some predefined constants, like:
{code}
String entityType = TimelineEntityType.YARN_CONTAINER.toString();
{code}
This will query for a specific type of timeline entities. We may want to
provide a different endpoint (like /ws/v2/applicationhistory) to support this
YARN specific use case.
In v1, we have AHSWebServices to support YARN specific application history
information. Maybe we would like to keep the same way?
This is my own (and subjective) idea. Feel free to let me know if you noticed
some critical things I'm missing... Thanks!

bq. One concern I have is, shall we expose the semantics of "containers" and
"appattempts" in timeline reader API level?
Sorry could not understand this fully. I assume that you are asking to create
another web service with different path like AHSWebService which internally
redirect the calls to getEntites in TimeLineReaderWebApp. So there will be
two @Path i.e */ws/v2/timeline* and */ws/v2/applicationhistory* exposed in
ATSv2. Is it ?
bq. Similar to the past AHS APIs, maybe we'd like to abstract a separate layer
of APIs for YARN to read data from timeline service?
Sorry I could not get it.

Thanks [~rohithsharma]! I took a deeper look into the patch. The overall
approach LGTM. One concern I have is, shall we expose the semantics of
"containers" and "appattempts" in timeline reader API level? To me, the
timeline API is independent from the actual use cases: it merely provides
concrete ways to retrieve timeline entities. Similar to the past AHS APIs,
maybe we'd like to abstract a separate layer of APIs for YARN to read data from
timeline service? Of course we can integrate the new "AHS REST API" layer in
the timeline reader server, but code-wise shall we separate the new APIs from
TimelineReaderWebService?
BTW, I set this JIRA to be patch available so that Jenkins can find the patch
and test it. If you want something otherwise please feel free to change it
back. Thanks!

bq. Currently not supported. What's the use case for this by the way ?
This is required for pagination. And more importantly fromId is must for
support for pagination. And also limit & fromId should be there in all the REST
end points.

Ah I just checked the v0 patch, the current approach to keep default limit to
be 100 unless specified seems fine. Is there a way to specify "unlimit"
(although not encouraged)? Thanks!

bq. FromId is something which filter need to support so from where to retrieve
the apps(not there now). For example , app-1 to app-10 are there. So if
fromId=app-5 then apps app-6 to app-10 should be retrieved. Is there any other
way to achieve this now?
Currently not supported. What's the use case for this by the way ?
This can be supported easily though, within the scope of a flow.

One potential problem of returning all apps in a cluster/containers in an app
attempt is that they may easily cause severe server slowness if not used
properly. In the past this became a great pain when Apache Ambari called the
default endpoint of AHS, when the total number of applications is extremely
large. I agree it is quite desirable to have the ability to "list all", but at
the same time we may want to consider restrict the number of returned entities
unless specified by the caller, or support paging, or both?

Attached a patch for supporting legacy API i.e retrieving containers for an
attempt-id i.e {{/apps/\{appid\}/appattempts/\{appattemptid\}/containers}}.
Basically, REST calls to getContainers method construct an infofilters
internally and retrieve the entities.

It is required to get all the apps in cluster. REST client will ask for limit
and fromId. FromId is something which filter need to support so from where to
retrieve the apps(not there now). For example , app-1 to app-10 are there. So
if fromId=app-5 then apps app-6 to app-10 should be retrieved. Is there any
other way to achieve this now?
bq. If merely list of apps within a cluster is required(without any other
information) we can probably serve this from app to flow table.
Not only app id's but also other information required. And currently the way I
see is need to get all the flows first and for each flows, retrieve apps. This
is something where client need to lot of REST calls constructing for each
flows.

Varun Saxena commented on YARN-5561:
Copying my comment over from YARN-5571.
If we have to support fetching all the apps within a cluster, upto a limit,
this currently is not advisable in HBase implementation as it would lead to a
full table scan or a very large scan. Because the API guarantees returning
entities in a descending order by created time. This would mean that we will go
through each row to determine the result set.
It is about taking one of the choices. Do we want to drill down to apps via
flows or list all the apps in a cluster.
We can discuss further in the team on this, depending on the use case. And see
if we can have some workaround.

Other option is publish the entities as string rather than object. The below
one is info value holds as object.
{code}
"SYSTEM_INFO_PARENT_ENTITY": {
"type": "YARN_APPLICATION",
"id": "application_1471931266232_0024"
}
{code}
This can split into below which is very much useful in filtering.

"SYSTEM_INFO_PARENT_ENTITY_TYPE": "YARN_APPLICATION"
"SYSTEM_INFO_PARENT_ENTITY_ID":"application_1471931266232_0024"

Looking into code base for reader for supporting these REST end points. I see
that ApplicationTable schema is defined with row key
*clusterId!userName!flowName!flowRunId!AppId*.
# */apps* without userId and flowName should be able to read. Currently it is
mandatory that to read apps to provide userId and flowName.
# */apps/\{app-id\}/app-attempts* can be redirect to existing getEntity for
YARN-APPLICATIOIN-ENTITY.
# */apps/\{app-id\}/app-attempt/\{app-attempt-id\}/containers*. As per design,
YARN_APPLICATION_ATTEMPT and YARN_CONTAINERS are stored as general entities.
Reading will be same as others user entities. I think there should be another
hbase table that stores YARN specific entities. Otherwise it is big overhead
for clients to parse output to know about its parent entity.

+ 1 on adding more rest endpoints. It makes things easier to query/script for.
As such in the list above, perhaps 2 and 3 can be combined such that 3 becomes
query params in 2.
As discussed in today's call, this jira might help with YARN-4343.
