-----------------------------------

Hi [~zjshen]
   bq. When an application is finished, the AM container is still alive for 
minutes. I didn't change my config that was used in 2.6 before. Not sure if it 
is a related issue.
I think this is MAPREDUCE-6311. All the time whenever MR job has run, AM jvm 
does not shutdown. Everytime AM expired event is triggered.
