Arun Suresh commented on YARN-6920:
-----------------------------------
Actually, let me take over this [~haibochen], if you don't mind.
On further investigation, it looks like the actual issue is due to the fact
that during container re-initialization, the container resources which should
have been reclaimed by the ContainerScheduler before re-launching the
re-initialized container, was never re-claimed - which resulted in a resource
leak.
This was not happening earlier either, but due to the fact that prior to
YARN-6706, if maxOppQueueLength == 0, we never even used to perform a resource
availability check, the ContainerManager test-cases used to pass :)
Will post the fix shortly along with some additional assertions.
