Description

once we restart nodemanager we see many logs like :
2015-12-28 11:59:18,725 WARN org.apache.hadoop.yarn.server.nodemanager.containermanager.ContainerManagerImpl: Event EventType: FINISH_APPLICATION sent to absent application application_1446103803043_9892

we find that the app containers are never started on NM and is released by AM after allocated.
