Wilfred Spiegelenburg commented on YARN-9194:
---------------------------------------------
Thank you for logging this jira [~xiaoheipangzi].
When I look at the logs I get the impression that the issue is in the way we
lock and or track the node:
{code}

org.apache.hadoop.yarn.server.resourcemanager.rmnode.RMNodeImpl: hadoop15:43450

...
2019-01-13 08:52:15,227 INFO
org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.ParentQueue:
assignedContainer queue=root usedCapacity=0.125 absoluteUsedCapacity=0.125
used=<memory:2048, vCores:1> cluster=<memory:16384, vCores:16>
2019-01-13 08:52:15,234 INFO
org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler:
Allocation proposal accepted
{code}
Based on this log there is a 4 second gap between allocation acceptance and the
node removal. The node was removed *4 seconds* before the allocation the
{{FiCaSchedulerNode}} was finished en the scheduler confirmed the allocation.
That looks strange: assigning a container on a node that has already been
removed. Based on this we probably should check the proposal and make sure that
it is declined when the node is removed.
I also don't think it is a good idea to fail the application in this case. The
container is never started and the failure is inside the scheduler. Failing an
application when that happens is I don't think the correct action.
