Subject [jira] [Commented] (YARN-5171) Extend DistributedSchedulerProtocol to notify RM of containers allocated by the Node
Date Tue, 21 Jun 2016 06:32:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15341211#comment-15341211
] 

Arun Suresh commented on YARN-5171:
-----------------------------------

With regard to the naming, I actually like the word *external* here since it implies that
the container was allocated externally w.r.t the RM scheduler... YARN-5215, i feel is more
about external resources rather than external scheduling..
I vote we keep the external and move on. If it clashes with YARN-5215, we can always change
it.

[~elgoiri], With regard to the test-case, can we also add the following test ?
# Get AM to request an OPP container
# Once Container is allocated, Get AM to release the container.
# Get AM to send couple more allocate reqs and wait for the released container to appear in
{{allocResponse.getCompletedContainersStatuses()}}

> Currently, the RM does not know about Containers allocated by the OpportunisticContainerAllocator
on the NM. This JIRA proposes to extend the Distributed Scheduler request interceptor and
the protocol to notify the RM of new containers as and when they are allocated at the NM.
The {{RMContainer}} should also be extended to expose the {{ExecutionType}} of the container.
