> In our cluster we set max-am-attempts to a very very large num, and
> unfortunately our am crash after launched, leaving too many completed
> container(AM container) in NM. completed container is removed from NM and
> NMStateStore only if container complete is passed to AM, but if AM couldn't
> be launched, the completed AM container couldn't be cleaned, and may eat up
> NM heap memory.
