Jian He commented on YARN-2005:
-------------------------------
Seems the patch will blacklist a node immediately once the AM container fails,
I think we may black list a node only after a configurable threshold ? Some
apps may still like to be re-started on the same node for reasons like data
locality - AM does not want to transfer the local data to a different machine
when restarted.
> Blacklisting support for scheduling AMs

> 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.
