Arun Suresh commented on YARN-5978:
-----------------------------------
Thanks for the patch [~kartheek].
Couple of nits:
* I think you can rollback the changes to hadoop-yarn-server-common/pom.xml
* In {{TestAMRMClient}}, some of the changes like the one in line 994, when the
timeout is commented can be rolled-back.
Also, in {{ContainerShceduler::onUpdateContainer()}} method, you should add
{{killOpportunisticContainers()}} before line 203 to ensure that any running
opportunistic containers are killed to make room for this promoted container.
Which reminds me:
I think we need 1 more test-case. probably in {{TestContainerSchedulerQueuing}}
- to test the above.
Essentially, we should have a situation where we have a full NM with a bunch of
Opportunistic containers running and some Opp containers queued. Then the
testcase should promote a queued Opp container, we should verify that it starts
running - and one/more of the running opportunistic containers is/are killed to
make room.
