> 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.
