Arun Suresh commented on YARN-1014:

Thanks for taking this up [~kasha]..

Id think this would be generally useful in trunk, but w.r.t YARN-2877, We were 
actually planning on getting the ContainersMonitor to kill/preempt 
opportunistic containers. This way, we can probably have more control over 
which containers are to be killed.

[~kkaranasos], thoughts ?
