Date Thu, 07 Apr 2016 01:30:25 GMT

sandflee commented on YARN-4924:
--------------------------------

thanks [~nroberts], another thought, seems it's not nessesary for NM to store FINISH_APP event,
for RM will check the running app when NM register, we just make sure that when NM register
RM, it had recovered all containers with best, yes? [~jlowe]

> It's probably a small window but we observed a case where the NM crashed and then a container
was not properly cleaned up during recovery.
