Arun Suresh commented on YARN-5171:
-----------------------------------
Thanks for the patch [~elgoiri]..
The general approach looks good, We would also need to ensure the following
though :
# Since the container is created outside the RM, the {{attemptResourceUsage}}
field in the {{SchedulerApplicationAttempt}} is not incremented (This is done
by the specific schedulers and is found in the specific implementation of the
SchedulerApplicationAttempt). I guess we should have a separate
{{attemptResourceUsageOpportunistic}} field introduced in the
SchedulerApplicationAttempt class, that is incremented when the
DistributedSchedulingService creates the RMConatiner.
# Similarly, we should modify the {{completeContainer()}} method in the
{{AbstractYarnScheduler}} to also decrement the
{{attemptResourceUsageOpportunistic}} of the corresponding app attempt if the
completed container was opportunistic (we can get that from the
{{ContainerStatus}})
> Extend DistributedSchedulerProtocol to notify RM of containers allocated by
> the Node

> 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.
