Description

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.
