Bikas Saha commented on YARN-2005:
----------------------------------
I believe the reverse case is also valid. A user may want to specify a locality
constraint for the AM but today that is ignored because its dropped from the am
resource request by the RM. Similarly, only the memory resource constraint is
used and others (cpu etc) are dropped. Perhaps this jira should tackle this
problem wholistically by fully respecting the resource request as specified in
the am container launch context.

> 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.
