The only jira that is left for this first phase is the documentation patch and YARN-4858. Both should be able to make 2.9.0. The rest of the feature is already in branch-2. I have split out some of the major features that still need to be finished in the shared cache into a phase 2 jira (YARN-7282). That being said, the core parts of this feature are committed and ready to be used in deployments that do not need phase 2 features. > truly shared cache for jars (jobjar/libjar) > --- > > Key: YARN-1492 > URL: https://issues.apache.org/jira/browse/YARN-1492 > Project: Hadoop YARN > Issue Type: New Feature >Affects Versions: 2.0.4-alpha >Reporter: Sangjin Lee >Assignee: Chris Trezzo > Attachments: shared_cache_design.pdf, shared_cache_design_v2.pdf, > shared_cache_design_v3.pdf, shared_cache_design_v4.pdf, > shared_cache_design_v5.pdf, shared_cache_design_v6.pdf, > YARN-1492-all-trunk-v1.patch, YARN-1492-all-trunk-v2.patch, > YARN-1492-all-trunk-v3.patch, YARN-1492-all-trunk-v4.patch, > YARN-1492-all-trunk-v5.patch > > > Currently there is the distributed cache that enables you to cache jars and > files so that attempts from the same job can reuse them.

Could you explain how the shared cache leverage the node manager local cache in detail? The shared cache leverages the local cache via the normal LocalResource API. The YARN application specifies a shared cache path that it received from the shared cache as the LocalResource URI. bq. Are those shared jars marked as PUBLIC? Yes, currently all resources in the shared cache are world readable, so they are in that sense public. However, at the node manager level you could set the visibilities to PRIVATE or APPLICATION. bq. Could you point me the source code that handle this? The shared cache uses the normal localization code path (see ResourceLocalizationService). For shared cache specific parts to upload a resource to the cache see SharedCacheUploader. If you want to see an example of how a YARN application can implement support for the shared cache, see MAPREDUCE-5951 for how map reduce does it. > truly shared cache for jars (jobjar/libjar) > --- > > Key: YARN-1492 > URL: https://issues.apache.org/jira/browse/YARN-1492 > Project: Hadoop YARN > Issue Type: New Feature >Affects Versions: 2.0.4-alpha >Reporter: Sangjin Lee >Assignee: Chris Trezzo > Attachments: shared_cache_design.pdf, shared_cache_design_v2.pdf, > shared_cache_design_v3.pdf, shared_cache_design_v4.pdf, > shared_cache_design_v5.pdf, shared_cache_design_v6.pdf, > YARN-1492-all-trunk-v1.patch, YARN-1492-all-trunk-v2.patch, > YARN-1492-all-trunk-v3.patch, YARN-1492-all-trunk-v4.patch, > YARN-1492-all-trunk-v5.patch > > > Currently there is the distributed cache that enables you to cache jars and > files so that attempts from the same job can reuse them.

The short answer is yes. YARN applications can leverage this feature to prevent relocalizing the same resources over and over again from both the client to hdfs as well as from hdfs to the node managers. The shared cache leverages checksuming and the node manager local cache to ensure applications can reuse resources that are already localized on node managers. See MAPREDUCE-5951 for mapreduce level support for the shared cache (which will hopefully be committed shortly to trunk and branch-2). Please let me know if you have any more questions.

Complete the refactor that removes SCMContext and ensures implementation details from the in-memory store are not leaked through the SCMStore interface. 2. Add a configuration parameter at the yarn level that allows operators to disallow uploading resources to the shared cache if they are not PUBLIC (currently resources are allowed if they are PUBLIC or owned by the user requesting the upload). 3. Ability to run SCM optionally as part of the RM. A few things that are important, but can be added post merge: 1. A levelDB store implementation. 2. Security. 3. ZK-based store implementation. Also, the consensus was that it seemed OK to let store implementations handle eviction policy logic. Having eviction policy logic span store implementations might be difficult and could cause store implementation details to leak through into the policies. For example, the in-memory store has to consider when it started up during cache eviction, where persistent stores may not need to. > truly shared cache for jars (jobjar/libjar) > --- > > Key: YARN-1492 > URL: https://issues.apache.org/jira/browse/YARN-1492 > Project: Hadoop YARN > Issue Type: New Feature >Affects Versions: 2.0.4-alpha >Reporter: Sangjin Lee >Assignee: Chris Trezzo > Attachments: YARN-1492-all-trunk-v1.patch, > YARN-1492-all-trunk-v2.patch, YARN-1492-all-trunk-v3.patch, > YARN-1492-all-trunk-v4.patch, YARN-1492-all-trunk-v5.patch, > shared_cache_design.pdf, shared_cache_design_v2.pdf, > shared_cache_design_v3.pdf, shared_cache_design_v4.pdf, > shared_cache_design_v5.pdf, shared_cache_design_v6.pdf > > > Currently there is the distributed cache that enables you to cache jars and > files so that attempts from the same job can reuse them.

Personally, I am okay with working on leveldb and zk stores post merge. My main concern is with providing a way to initialize the store, as we don't have a good answer for long-running apps and it will not be required when using leveldb and zk implementations for non-HA and HA cases. I would rather avoid that piece completely. I am okay with having an in-memory store that the tests exercise and has a trivial recovery. Having a "real" store though would definitely boost people's confidence at merge time :) > truly shared cache for jars (jobjar/libjar) > --- > > Key: YARN-1492 > URL: https://issues.apache.org/jira/browse/YARN-1492 > Project: Hadoop YARN > Issue Type: New Feature >Affects Versions: 2.0.4-alpha >Reporter: Sangjin Lee >Assignee: Chris Trezzo > Attachments: YARN-1492-all-trunk-v1.patch, > YARN-1492-all-trunk-v2.patch, YARN-1492-all-trunk-v3.patch, > YARN-1492-all-trunk-v4.patch, YARN-1492-all-trunk-v5.patch, > shared_cache_design.pdf, shared_cache_design_v2.pdf, > shared_cache_design_v3.pdf, shared_cache_design_v4.pdf, > shared_cache_design_v5.pdf, shared_cache_design_v6.pdf > > > Currently there is the distributed cache that enables you to cache jars and > files so that attempts from the same job can reuse them.

A couple of questions: bq. 2. The choice of SCM store should be transparent to the rest of SCM code. It would be better to define an interface for the SCMStore similar to the RMStateStore today. To clarify the above point. An interface does exist in the current implementation (see SCMStore.java in YARN-2180), and all SCMStore implementations should be based off of that. Unfortunately some implementation details from the in-memory store have leaked through via the SCMContext object. I am working on an update to improve the interface so that an SCMContext object is no longer needed and all implementation details are hidden behind SCMStore.java. Does your above point mean that you are looking for a state machine-based interface like RMStateStore, or do you see additional issues with the SCMStore interface outside of the SCMContext fix? bq. 3. Defaulting to the in-memory store requires providing a way to initialize the store with currently running applications and cached jars, which is quite involved and not so elegant either. I propose implementing leveldb and zk stores. We could default to leveldb on non-HA clusters, and ZK store for HA clusters if we choose to embed the SCM in the RM. Do you see the leveldb and zk stores as blockers to merging into trunk/2.6 or would an in-memory store with the interface fixes mentioned above be enough initially? Leveldb and ZK stores could be easily added post-merge in an incremental way as additional SCMStore implementations. > truly shared cache for jars (jobjar/libjar) > --- > > Key: YARN-1492 > URL: https://issues.apache.org/jira/browse/YARN-1492 > Project: Hadoop YARN > Issue Type: New Feature >Affects Versions: 2.0.4-alpha >Reporter: Sangjin Lee >Assignee: Chris Trezzo > Attachments: YARN-1492-all-trunk-v1.patch, > YARN-1492-all-trunk-v2.patch, YARN-1492-all-trunk-v3.patch, > YARN-1492-all-trunk-v4.patch, YARN-1492-all-trunk-v5.patch, > shared_cache_design.pdf, shared_cache_design_v2.pdf, > shared_cache_design_v3.pdf, shared_cache_design_v4.pdf, > shared_cache_design_v5.pdf, shared_cache_design_v6.pdf > > > Currently there is the distributed cache that enables you to cache jars and > files so that attempts from the same job can reuse them.

Chris and I discussed the design and current implementation offline. A couple of comments in that discussion: # I like the idea of having a separate daemon for SCM, but if it is not very resource (memory) intensive, it might make sense to embed it in the RM by default. This takes care of HA etc. for free. We can do this at the end. # The choice of SCM store should be transparent to the rest of SCM code. It would be better to define an interface for the SCMStore similar to the RMStateStore today. # Defaulting to the in-memory store requires providing a way to initialize the store with currently running applications and cached jars, which is quite involved and not so elegant either.

Chris Trezzo commented on YARN-1492:
The patch is now +1 overall. Please note that I have broken up this patch into
smaller patches that are located in each of the sub tasks on this issue. If you
would like to try out the feature, here are the simple requirements for setting
up the shared cache:
1. In HDFS, create the shared cache root directory (set to /sharedcache by
default).
2. In mapred-site.xml add the following parameter:
{noformat}
mapreduce.job.sharedcache.mode
jobjar,libjars,files,archives
A comma delimited list of resource categories to submit to the shared cache.
The valid categories are: jobjar, libjars, files, archives.
If "disabled" is specified then the job submission code will not use
the shared cache.
{noformat}
3. In yarn-site.xml add the following parameter:
{noformat}
Whether the shared cache is enabled
yarn.sharedcache.enabled
enabled
{noformat}
4. Start the SCM (shared cache manager) using the regular yarn shell scripts.
{noformat}
./yarn-daemon.sh start sharedcachemanager
{noformat}
With this setup all job jars, lib jars, files and archives specified by
MapReduce jobs will be automatically cached.

Would SCM be a single point of failure? If yes, would anyone of the following approaches make sense. Currently, yes, but it will be able to restart while preserving the current metadata about the cache. While the SCM is down, the shared cache would not be useable, but this would not affect job submission or execution (i.e. the applications could just continue operating without it using normal resource submission). bq. Make SCM an AM. From YARN-896, the only sub-task that affects this would be the delegation tokens. This is an interesting idea. We shied away from this initially because the SCM will be a long running process. Also, with this approach what would be your recommendation for service discovery? Clients would need to know which machine the SCM is running on. [~sjlee0] also brought up an interesting point: running it as an AM would make local persisted state tricky. bq. Add an SCMMonitorService to the RM. If SCM is enabled, this service would start the SCM on one of the nodes and monitor it. This sounds like a good idea. Originally we wanted to avoid having dependencies from the RM to the SCM. The HA/Failover part of the design needs to be expanded upon in the document (the first priority was to have SCM stateful restart). bq. SCM Cleaner Service - the doc mentions the tension between frequency of cleaner and load on the RM. Can you elaborate? I was of the opinion that the RM is not involved in the caching at all. When the cleaner service runs it must check with the RM which application ids belong to applications that are no longer running. This requires the SCM to query the RM. I can update the document and talk about this more explicitly. bq. Cleaner protocol doesn't mention when the cleaner lock is cleared. I assume it is cleared on each exit path. Correct. When the cleaner deletes the entry row in the SCM table the cleaner lock is deleted for that entry as well. I will update the document to clarify. bq. Nit: ZK-based store - we can may be do this in the JIRA corresponding to the sub-task - how would this look like? I can write up a more detailed design section for this in the document. We are also planning to have a local store as well (leveraging something like LevelDB or HSQLDB). bq. More nit-picking: The rationale for not using in-memory and reconstructing seems to come from long-running applications. Given long-running applications don't benefit from the shared cache as much as the shorter ones, is this a huge concern? The concern around the in-memory/reconstruction approach was more about long running applications holding the cleaner service hostage. It seems difficult for the SCM to prevent a long running application from using the shared cache. If a long running application decides to use the shared cache for a resource and the SCM restarts/crashes, then the cleaner service will not be able to run until the application has terminated. This seemed like a big enough vulnerability to block this approach. > truly shared cache for jars (jobjar/libjar) > --- > > Key: YARN-1492 > URL: https://issues.apache.org/jira/browse/YARN-1492 > Project: Hadoop YARN > Issue Type: New Feature >Affects Versions: 2.0.4-alpha >Reporter: Sangjin Lee >Assignee: Sangjin Lee > Attachments: shared_cache_design.pdf, shared_cache_design_v2.pdf, > shared_cache_design_v3.pdf, shared_cache_design_v4.pdf, > shared_cache_design_v5.pdf > > > Currently there is the distributed cache that enables you to cache jars and > files so that attempts from the same job can reuse them.

[~sjlee0] and I will update the doc to incorporate the helpful feedback. Specific comments are in-line. bq. The public localizer will only localize files that are publicly available, however the staging directory is not publicly available. Clients must upload publicly localized files elsewhere in order for that to work, but files outside of the staging directory won't be automatically cleaned when the job exits. Good point. I will update the doc. One way to address this, is to modify the conditions for uploading a resource to the shared cache. The resource either has to be publicly readable or owned by the user requesting the localization. The later condition would require strong authentication to run securely. The staging directory example would fall into this category. I am not extremely familiar with the security part of the code base, but I will look into this more and update the document. bq. There's a race between the NM uploading the file to the shared cache area and the local dist cache cleaner removing the local file. Since uploading a resource to the shared cache is asynchronous and not required for job submission/execution to succeed, adding the resource to the cache can be best effort. If the localization service loses the race with the cache cleaner then the resource simply won't make it into the cache. Does that sound reasonable? bq. How parallel will the NM upload process be – is it serially uploading the resources for each container and between containers? This is a good question. One option would be to make this tunable using a thread pool. The important part is that since the NM upload process is asynchronous and not critical for application execution, it becomes an implementation detail. bq. Is the cleaner running as part of the SCM? If so I don't think it necessary to store the cleaner flag in the persisted state, and that would be a bit less traffic to the store while cleaning. Agreed. I will update the doc. bq. It might be nice to provide a simpler store setup for the SCM for smaller clusters or those not already using ZK for other things (e.g.: HA) Something like a leveldb store or simple local filesystem storage would suffice since those don't require separate setup. Agreed. The plan is to have a very clean interface between the storage mechanism and the rest of the Manager. This will allow us to have multiple stores and we can definitely have a simpler store. bq. The cleaner should handle files that are orphaned in the cache if the NM fails to complete the upload. Could use a timeout based on the file timestamp or other mechanisms to accomplish this. Agreed. I will make this more explicit in the doc. The design is that the cleaner service iterates over all entries in HDFS, not just the entries the SCM knows about. This will ensure that orphaned files/entries will be handled by the cleaner service. Modification time of the entry directory in HDFS can be used by the cleaner service to determine staleness. bq. What criteria will clients use to decide if files are public? As-is this doesn't seem to address the original goals of the JIRA since hardly anything is declared public unless already in a well-known place in HDFS today. I'd like the design to also state any proposed changes to the behavior of the job submitter's handling of the dist cache during job submission if there are any. I will add a section to the document about application specific changes to MapReduce. The shared cache api allows an application to add resources to the shared cache on a per-resource basis, which should allow for any application-level resource caching policy. That being said, we can elaborate more on how MapReduce will specifically support the shared cache. bq. Nit: It should be made clearer that the client cannot notify the SCM that an application is not using a resource until the application has completed, or we risk the cleaner removing the resource while it is still in use by the application. The client protocol steps read as if the client can submit and then immediately notify the SCM if desired. Thanks.

In the client protocol, if a cleaner instance (or run) starts after R2 and before R2', the client wouldn't know of this cleaner's existence. That's why step R1 exists. Since the client lock is dropped *before* the client inspects the cleaner lock, even if the cleaner starts between R2 and R2' the cleaner simply skips this entry in favor of the client. Having said that, we are currently looking at the design again to better address the issue of security and other aspects. So it is likely some of these design choices may be revisited. > truly shared cache for jars (jobjar/libjar) > --- > > Key: YARN-1492 > URL: https://issues.apache.org/jira/browse/YARN-1492 > Project: Hadoop YARN > Issue Type: New Feature >Affects Versions: 2.0.4-alpha >Reporter: Sangjin Lee >Assignee: Sangjin Lee > Attachments: shared_cache_design.pdf, shared_cache_design_v2.pdf, > shared_cache_design_v3.pdf, shared_cache_design_v4.pdf > > > Currently there is the distributed cache that enables you to cache jars and > files so that attempts from the same job can reuse them.

If the Cleaner crashes, the corresponding connection to ZK is severed, and all locks are automatically cleaned up (if using ephemeral nodes). As others have mentioned earlier, I think it is okay to assume one ZK quorum running. For instance, RM HA requires this. # We should probably mandate running CleanerService if shared-cache is enabled, and should run as part of the RM and periodically. > truly shared cache for jars (jobjar/libjar) > --- > > Key: YARN-1492 > URL: https://issues.apache.org/jira/browse/YARN-1492 > Project: Hadoop YARN > Issue Type: New Feature >Affects Versions: 2.0.4-alpha >Reporter: Sangjin Lee >Assignee: Sangjin Lee > Attachments: shared_cache_design.pdf, shared_cache_design_v2.pdf, > shared_cache_design_v3.pdf, shared_cache_design_v4.pdf > > > Currently there is the distributed cache that enables you to cache jars and > files so that attempts from the same job can reuse them.
