Subru Krishnan commented on YARN-5966:
--------------------------------------
Thanks [~asuresh] for the patch. I looked at it and have a couple of comments:
* In the {{AMRMClientImpl}}, I feel it'll be simpler/cleaner if we validate
and fail fast if required based on the {{ContainerUpdateType}} enum instead of
the implicit auto-correction. It should also be very straightforward to have
corresponding coverage in tests.
* I have few _optional_ suggestions for
{{TestOpportunisticContainerAllocation}} - since you have done the
heavy-lifting of adding the harness code, you should consider adding tests for
idempotency checks (GUARANTEED --> GUARANTEED and OPPORTUNISTIC -->
OPPORTUNISTIC). We only have positive test cases, I feel promotion especially
need not necessarily be satisfied and so will be good to have tests covering
these rejection scenarios.
* A separate thought I had is how do we handle promotion/demotion requests
where the container has completed during the interim?
