Varun Saxena commented on YARN-5548:
------------------------------------
Few comments.
# Can we set state store as Memory RM state store in setup of test class if all
tests use it? MockRM would automatically convert it. Creating
MockRMMemoryStateStore object explicitly in tests is not really required. We
will have to enable recovery if we do that though.
# Is MemoryRMStateStore even required in TestRMContainerAllocator,
TestRMHA#testFailoverClearsRMContext,
TestContainerResourceUsage#testUsageWithMultipleContainersAndRMRestart and
TestCapacityScheduler tests?
# I get a failure for TestAMRestart#testRMAppAttemptFailuresValidityInterval as
it does not use MockRMMemoryStateStore. We should use it.
