Anubhav Dhoot commented on YARN-2005:
-------------------------------------

Hi [~kasha] thanks for your comments.

2.4 - we do not need to update the systemBlacklist as its updated by the RMAppAttemptImpl#ScheduleTransition
call every time to the complete list. 
11, 12 - The changes were needed because now we need a valid submission context for isWaitingForAMContainer.
9 - Is needed by the new test added in TestAMRestart.
8.3 - Yes i can file a follow up for that
Addressed rest of them

> It would be nice if the RM supported blacklisting a node for an AM launch after the same
node fails a configurable number of AM attempts.  This would be similar to the blacklisting
support for scheduling task attempts in the MapReduce AM but for scheduling AM attempts on
the RM side.
