Subject [jira] [Commented] (YARN-5171) Extend DistributedSchedulerProtocol to notify RM of containers allocated by the Node
Date Wed, 22 Jun 2016 02:38:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15343231#comment-15343231
] 

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

Thanks for the updated patch [~elgoiri]

The updated test case looks good, few comments:
# to ensure that we verify the fact that the AM is notified of the completed containers, you
should probably add an {{Assert.assertTrue(released);}} after you exit from the for loop.

# You can remove the TODO.

With regard to the naming, I now feel the best way to avoid conflicts is to probably rename
{{isExternallAllocated()}} to {{isAllocatedViaDistributedScheduler()}} and similarly, the
{{allocatedResourcesExternal}} to {{allocatedResourcesViaDistSched}}

> 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.
