Sunil G commented on YARN-2005:
-------------------------------

Thank you [~steve_l] for sharing your thoughts.
I completely agree with your point that AM also has to give specific return type as per an
agreement with RM so that we can take a decision more wisely. Still I feel it will be completely
upto AM to do the handling.
If its ok, I think we can spin this return code handing from as a ticket and will try make
progress in same.

> 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.
