Weiwei Yang commented on YARN-8984:
-----------------------------------
Thanks for the updates [~fly_in_gis], it almost seems good to me. One thought
if we remove that null check
{code}
List<SchedulingRequest> schedReqs =
outstandingSchedRequests.get(container.getAllocationTags());
{code}
now this seems to be possible to throw NPE, when container.getAllocationTags()
is null.
> AMRMClient#OutstandingSchedRequests leaks when AllocationTags is null or empty
