Anubhav Dhoot updated YARN-2005:
--------------------------------
    Attachment: YARN-2005.002.patch

Addressed the test failure. Unmanaged AM also executes the AMLaunched 
Transition which was causing the the allocate call that removes AM blacklist. 
Changed it so it does not execute for unmanaged AM.

> 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.
