[jira] [Commented] (HADOOP-15515) adl.AdlFilesystem.close() doesn't release locks on open files

Chris Douglas commented on HADOOP-15515:
bq. Could you please suggest if the openFileStreams modification is disallowed
and create/append/creteNonRecursive should fail with IOException? Looked at
DfsClient code and operation's after FileSystem.Close is allowed.
Throwing {{IOException}} makes sense to me, as this looks like a resource leak.
I'm not sure if {{DFSClient}} also has a resource leak, or if it's significant
that this is handled one level up for ADLS (i.e., as part of the
{{FileSystem}}, not the client it wraps).
Aside: please don't delete attachments. Doing so orphans the discussion about
them.

It only affects 3 wasb tests in trunk-2. But sent out a JIRA and made it consistent with trunk To be clear (please correct if I've misunderstood), this JIRA updated a live test to match the exception text from the updated client library, but it missed a case. HADOOP-15533 addresses this (are three of these tests failing, now?). Would you mind updating HADOOP-15533 to include more context?

Chris Douglas commented on HADOOP-15515:
I looked more closely at the synchronization, and there may be some edge cases
that aren't covered. Specifically:
* if {{close}} is holding the lock on {{openFileStreams}} while cleaning up, if
another thread is waiting on its monitor then it may add elements to the
collection after the filesystem is closed.
* In {{close}}, exceptions while closing streams may prevent the intended
behavior. While {{close}} should be
[idempotent|https://docs.oracle.com/javase/8/docs/api/java/io/Closeable.html#close--]
(so a closed stream won't put this in an unrecoverable state), if any stream
throws an exception, then subsequent entries will not be closed. The intended
behavior is probably closer to {{IOUtils::cleanup}}, which swallows
{{IOException}}.
* The lock order (i.e., hold {{openFileStreams}} while closing a stream, or
hold one at at time) should be documented.
* {{openFileStreams}} can be a final field

Chris Douglas commented on HADOOP-15515:
Moving to common, as this doesn't affect HDFS. v002 seems to implement a
pattern similar to
[DFSClient|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DFSClient.java#L626].
bq. As I can't see a way to force lease recovery in this situation
As long as this is only an optimization- and a client failing to release the
lock won't wedge the system- this looks OK. I checked the [client
docs|https://azure.github.io/azure-data-lake-store-java/javadoc/], and it looks
like the ADL client doesn't have a {{close}} method, so presumably it's not
tracking open streams and this is correct.
If there's no other feedback I'll commit this soon.

[~Jim_Brennan] {{Configuration::getStrings}} is a convenience method, but the
delimiter is neither configurable nor escapable. This JIRA proposes to enhance
the convenience method. MAPREDUCE-7069 covers this? I skimmed the patch, but
might have missed the relevant code.

Thanks [~shanyu]. Running this through Jenkins.
We could add a unit test to signal that a change to the default behavior could
affect these FS implementations, but that should be implied.

Chris Douglas commented on HADOOP-15320:
bq. I know s3 "appears" to work, but I'm not actually confident that everything
is getting the splits right there.
Me either, but 1.5h to generate synthetic splits is definitely wrong. If we
develop a new, best practice for object stores, then we can apply that across
the stores we support. The {{Blocklocations[]}} return type is pretty
restrictive, but we could probably do better.
bq. The one I want you look at is: Spark, CSV, multiGB: SPARK-22240 . That's
what's been niggling at me for a while.
Maybe I'm missing the bug. Block locations are hints for locality, not format
partitioning. In that JIRA: gzip is not splittable, so a single reader is
correct, absent some other preparation (saving the dictionary at offsets,
writing zero-length gzip files as split markers, etc.). In general, framework
parallelism should not rely exclusively on block locations...

[jira] [Commented] (HADOOP-14600) LocatedFileStatus constructor forces RawLocalFS to exec a process to get the permissions

Chris Douglas commented on HADOOP-14600:
bq. Without realizing you had already fixed this issue, I put a patch up in
HADOOP-15337 that shows the alternative implementation approach. Sorry again
for being so late to the conversation, not intending to step on toes.
No worries. If the approach in HADOOP-15337 is more portable, performs
comparably, and is equivalent, then let's take the simpler approach. Where
applicable, do the unit tests on this issue pass in HADOOP-15337, on
Linux/MacOS/Windows?

Chris Douglas commented on HADOOP-15320:
What testing has been done with this, already?
bq. do think it will need be bounced past the various tools, including: hive,
spark, pig to see that it all goes OK. But given S3A is using that default with
no adverse consequences, I think you'll be right.
Wouldn't one expect the same results, if the pattern worked for S3A? One would
expect to find framework code that is unnecessarily serial after this change.
What tests did S3A run that should be repeated?
bq. which endpoints did you run the entire hadoop-azure and
hadoop-azuredatalake test suites?
Running these integration tests is a good idea. It's why they're there, after
all.

Chris Douglas commented on HADOOP-15292:
Instead of passing a flag to {{readBytes}}, this can just call {{seek()}}
outside the loop (and include the {{getPos() != position}} optimization).
[~ste...@apache.org] are you set up to test S3? {{pread}} happens to have an
expensive implementation in HDFS (and other {{FileSystem}} impls), but creating
a test for distcp to ensure the {{PositionedReadable}} APIs aren't used seems
excessive.
bq. Not sure if it's worth extending that unit test to track how many times we
open the stream.
>From the description, it's inside the DN where {{pread}} creates multiple
>streams. IIRC the position of the stream isn't updated when using PR APIs. If
>the stream were shared that could be an issue, but that's not in the design.
>In HDFS, updating the set of locations for each read (without checking the
>distcp invariants) is also unused, here.
Demonstrating the fix with a demo in HDFS would be sufficient for commit, IMO.
It might be possible to add a test around the command itself to ensure the
{{seek()}} is correct on retry, but wiring the flaw into a test would require a
{{MiniDFSCluster}}.

lgtm. Do we need to change our [release
process|https://wiki.apache.org/hadoop/HowToRelease/] to update these branches?
Or will that happen implicitly? The patch in HADOOP-15256 looks like the
version is hard-coded in the Dockerfile, so I'm not sure I'm following how we
maintain the set of valid release targets from the ASF repo.
I'd expect that downstream, one could specify 2 (implicitly the latest 2.x.y),
2.8 (implicitly the latest 2.8.y) or 2.8.3 (exact). Is that the case?

[jira] [Commented] (HADOOP-14898) Create official Docker images for development and testing features
[
https://issues.apache.org/jira/browse/HADOOP-14898?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16381133#comment-16381133
]
Chris Douglas commented on HADOOP-14898:
bq. file a ticket with INFRA so that they can push this image as an Apache
Image to DockerHub. This will allow INFRA to push these dockerHub Images if and
when we make the changes. That is, we will have official Apache base images
which can be trusted by end-users and updated with various releases if needed.
Sorry, still catching up on this. We should only release official images of
releases, since that's the only artifact licensed for downstream use by a PMC
vote. The infra process linked through the document (INFRA-12781) wasn't clear
to me. We create branches- this proposes a base image, {{hadoop2}}, and
{{hadoop3}}- and that will be pushed to the ASF repo on Docker Hub? Presumably
these are just the head of versioned images, each corresponding to a release?

> TL;DR: I propose to create official hadoop images and upload them to the
> dockerhub.
> GOAL/SCOPE: I would like improve the existing documentation with easy-to-use
> docker based recipes to start hadoop clusters with various configuration.
> The images also could be used to test experimental features. For example
> ozone could be tested easily with these compose file and configuration:
> https://gist.github.com/elek/1676a97b98f4ba561c9f51fce2ab2ea6
> Or even the configuration could be included in the compose file:
> https://github.com/elek/hadoop/blob/docker-2.8.0/example/docker-compose.yaml
> I would like to create separated example compose files for federation, ha,
> metrics usage, etc. to make it easier to try out and understand the features.
> CONTEXT: There is an existing Jira
> https://issues.apache.org/jira/browse/HADOOP-13397
> But it’s about a tool to generate production quality docker images (multiple
> types, in a flexible way). If no objections, I will create a separated issue
> to create simplified docker images for rapid prototyping and investigating
> new features. And register the branch to the dockerhub to create the images
> automatically.
> MY BACKGROUND: I am working with docker based hadoop/spark clusters quite a
> while and run them succesfully in different environments (kubernetes,
> docker-swarm, nomad-based scheduling, etc.) My work is available from here:
> https://github.com/flokkr but they could handle more complex use cases (eg.
> instrumenting java processes with btrace, or read/reload configuration from
> consul).
> And IMHO in the official hadoop documentation it’s better to suggest to use
> official apache docker images and not external ones (which could be changed).
> {code}
> The next list will enumerate the key decision points regarding to docker
> image creating
> A. automated dockerhub build / jenkins build
> Docker images could be built on the dockerhub (a branch pattern should be
> defined for a github repository and the location of the Docker files) or
> could be built on a CI server and pushed.
> The second one is more flexible (it's more easy to create matrix build, for
> example)
> The first one had the advantage that we can get an additional flag on the
> dockerhub that the build is automated (and built from the source by the
> dockerhub).
> The decision is easy as ASF supports the first approach: (see
> https://issues.apache.org/jira/browse/INFRA-12781?focusedCommentId=15824096=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15824096)
> B. source: binary distribution or source build
> The second question is about creating the docker image. One option is to
> build the software on the fly during the creation of the docker image the
> other one is to use the binary releases.
> I suggest to use the second approach as:
> 1. In that case the hadoop:2.7.3 could contain exactly the same hadoop
> distrubution as the downloadable one
> 2. We don't need to add development tools to the image, the image could be
> more smaller (which is important as the goal for this image to getting
> started as fast as possible)
> 3. The docker definition will be more simple (and more easy to maintain)
> Usually this approach is used in other projects (I checked Apache Zeppelin
> and Apache Nutch)
> C. branch usage

I don't have access to an SELinux system and haven't even tried to use it since
2004. [~aw]?
Superficially:
* The comment could explain what this is working around, rather than a pointer
to the blog point
* Similarly, explaining what :z does might be useful
* Some {{bats}} unit tests exist for the shell code. Are there any useful tests
one could write for this?
* (trivial) {{\{split($3,ver,".");print ver[1]"."ver[2]\}}} could match

Chris Douglas commented on HADOOP-15204:
bq. I find getTimeDuration API extremely intuitive, hence imitating that for
this API
Soright; I only mention it as relevant context.
bq. Rounding causes a significant loss when we convert from x bytes to y
exabytes. Hence I voted for the least element of surprise and decided to return
double
Is it sufficient for the caller to provide the precision? If the caller wants
petabytes with some decimal places, then they can request terabytes. If they
want to ensure the conversion is within some epsilon, then they can request the
value with high precision and measure the loss. Even rounding decisions can be
left to the caller. Instead of passing this context into {{Configuration}} (or
setting defaults), its role can be limited to converting and scaling the
stringly-typed value.
Similarly:
bq. That would let me return something like -1 to mean "no value set", which I
can't do with the current API.
{{Configuration}} supports that with a raw {{get(key)}}. It's only where we
have the default in hand that it provides typed getters.
bq. This is the curse of writing a unit as a library; we need to be cognizant
of that single use case which will break us. Hence I have used bigDecimal to be
safe and correct and return doubles. It yields values that people expect.
Sure, I only mention it because it differs from {{getTimeDuration}}. With
{{TimeUnit}}, a caller could, with low false positives, check if the result was
equal to max to detect overflow. Doing that here would have a higher false
positive rate, so the {{BigDecimal}} approach with explicit precision is
superior.
Minor:
* In this overload:
{noformat}
+ public double getStorageSize(String name, String defaultValue,
+ StorageUnit targetUnit) {
{noformat}
Does this come up often? The {{getTimeDuration}} assumes that the default will
be in the same unit as the conversion. So in your example, one would write
{{getTimeDuration("key", 5000, MEGABYTES)}}. It's less elegant, but it type
checks.
* I'd lean toward {{MB}} instead of {{MEGABYTES}}, and similar. Even as a
static import, those are unlikely to collide and they're equally readable.

Chris Douglas commented on HADOOP-15151:
Thanks, [~rybkine]. While {{MapFile}} has some odd quirks, it's maintained by
the project mostly for compatibility with older applications. Improving the
code quality may not be a good use of your time. If you're interested in file
formats generally, you may want to check out the ORC and Parquet projects.
Of course, if that impression is mistaken and {{MapFile}} is important to you,
please feel free to open JIRAs to improve it (provided it continues to
read/write files compatible with the existing format).

Chris Douglas commented on HADOOP-15204:
bq. As the author of HADOOP-8608, I would appreciate any perspectives you have
on this JIRA.
I find the API intuitive, but that is not universal (e.g., HDFS-9847).
Explaining it has taken more cycles than I expected, and perhaps more than a
good API should.
* {{TERRABYTES}} is misspelled.
* Is {{long}} insufficient as a return type for {{getStorageSize}}? I
appreciate future-proofing, but for {{Configuration}} values, that's what, ~8
petabytes? I haven't looked carefully at the semantics of {{BigDecimal}}, but
the comments imply that {{setScale}} is used to guarantee the result will fit.
An overload of {{setStorageSize}} taking {{double}} might make sense, as would
using doubles in the overload of {{String}}.
* Why
[ROUND_UP|https://docs.oracle.com/javase/8/docs/api/java/math/BigDecimal.html#ROUND_UP]
of the options? Just curious.
* {{TimeUnit}} uses min/max values for Long (e.g.,
[TimeUnit::toNanos|https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/TimeUnit.html#toNanos-long-])
for overflow/underflow. Storage units are more likely to be exact powers of
two so that may not be appropriate.

Thanks for the patch, Duo. Are there advantages to writing this as a new
submodule, as in [^HADOOP-15190.01.patch]? HADOOP-14663 seems to achieve the
same objective, and we wouldn't need to update {{hadoop-coverage}} when we add
new submodules.
While the two tools measure coverage
[differently|http://openclover.org/doc/manual/4.2.0/general--comparison-of-code-coverage-tools.html],
either would be suitable. OpenClover uses ALv2, JaCoCo uses the
[EPL|https://www.apache.org/legal/resolved.html#category-b]; no significant
difference in our use. Is there a strong argument in favor of one over the
other?

[jira] [Commented] (HADOOP-15140) S3guard mistakes root URI without / as non-absolute path

]
Chris Douglas commented on HADOOP-15140:
I can't claim any grand insight, unfortunately. The semantics of an empty path
in the URI aren't crisp, since {{FileSystem}} instances maintain working/home
directories as context to resolve relative paths. In the past, that's gotten in
the way of defining clearer semantics, since FS overrides don't compose
compatibly. It's one of the reasons {{FileContext}} tried to move all the path
manipulation up a level, so the FS implementations only deal with absolute URIs
(IIRC, [~sanjay.radia] may have a clearer memory of this).
bq. To clarify the failure only occurs when passing a URI as an argument to the
Path constructor. Otherwise this is handled properly.
Can you expand on this?
bq. this surfaces in code which has a path p like s3a://bucket/file.txt and you
can getFileStatus(p.getParent()). The key of that parent is being mapped to "/"
and then s3guard is failing.
If I understand you, the path component of the URI should be resolving to "/",
which s3guard should resolve (even as a special case). Is it getting dropped?

Chris Douglas commented on HADOOP-15117:
bq. In AbstractContractPathHandleTest, do we need the if checks in the catch
after 180? We should've made sure those were true before. Are we covering
anything there?
Yes, that's where the test verifies that if an exception was thrown, it must be
because the rename or the modification was disallowed (because it's the
expression in the {{try}} that throws). If one is allowed, then it must have
been the other that caused the exception. In the case where both are
disallowed, we don't need an assertion because we've already checked both
conditions.
bq. Can we describe the serialize in TestHDFSContractPathHandle? Maybe move it
from Boolean to boolean too.
Sure, I'll add a comment. IIRC the change to {{Boolean}} was in service of an
invocation problem from {{Parameterized}}, but it might have been trying to
work around the {{name}} issue. I'll make sure it's necessary.

Attachment: HADOOP-15117.001.patch
Thanks for taking a look, [~elgoiri].
bq. Should we make sure we trigger the exception? For example, should testMoved
have a fail() after the verifyRead() that expects exceptions?
Instead of the try/fail, catch/ignore pattern this checks the option to
determine if the exception should have been thrown (and vice versa). The
{{verifyRead}} ensures the referent is correct with the expected content.
bq. We do the serialization of the PathHandle a bunch of times in the tests,
I'm not sure we should add it to the handle itself but wrapping it in a
function may make sense.
Good point. Changed whether the handle is first serialized to be another
parameter for the tests. Either {{Paramaterized}} has a bug, or I'm using the
naming incorrectly, because including this parameter in the name causes odd
test failures. As-is, it's enough for someone to figure out what's going wrong.
bq. Similarly to what you do in testChangedAndMoved(), you could split (with
extra lines), the part that does the changes/moves from the ones that do the
checks.
Done
bq. Does it make sense to fail() in the unreachable statement case for
getHandleOrSkip()
Unfortunately the return statement is still required. It really is unreachable
if {{skip}} does what it's supposed to do.

Chris Douglas commented on HADOOP-15106:
bq. Is there any unit test covering this?
Yes, the contract tests. I added more checks as part of HDFS-12882, but they're
not exhaustive. The negative cases are updated to catch
{{InvalidPathHandleException}} instead of {{IOException}} in the patch.
bq. How about moving InvalidPathHandleException above IOException in the
javadoc to be consistent with others like getFileStatus (e.g.,
FileNotFoundException goes above IOException)
Sure, np.

Fixed checkstyle. The unit tests failures are related, but the failure was in
removing the {{final}} modifier from {{getPathHandle(Path,HandleOpt...)}}. I'd
