Subject [jira] [Commented] (YARN-5171) Extend DistributedSchedulerProtocol to notify RM of containers allocated by the Node
Date Wed, 15 Jun 2016 16:33:09 GMT

    [ https://issues.apache.org/jira/browse/YARN-5171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15332035#comment-15332035

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

bq. Not sure if we should introduce in this JIRA the methods addRMContainer and removeRMContainer
in SchedulerApplicationAttempt
I don't really see why that would be too much of a problem.. Ideally I would have liked to
make it package protected, but since it gets called from the {{DistributedSchedulingService}},
which is in another package, that wont work.

bq. Also naming should reveal that they have to do with opportunistic scheduling, in case
we decide to keep them
Again, id prefer it as it is.. since thats what the method actually does

> 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.
