Jian He commented on YARN-2005:
-------------------------------
sorry for the late response.
I feel a simpler way is to do this inside the scheduler. RMApp and RMAppAttempt
need not be involved in the loop.
This way, the YarnScheduler interface can also avoid exposing a public
updateBlackList interface.
The SchedulerApplication can hold a reference to the blacklisted nodes.
AppSchedulerInfo can consult this reference for blacklisted nodes.

> 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.
