Does this constant exist all the way back to Hadoop 2.2? IIRC preemption was added later.

@vanzin yes its been there since 2.1.1-beta. Here is the JIRA which added that constant: https://issues.apache.org/jira/browse/YARN-1049

Note that the AllocateResponse also contains PreemptionMessage which is list of containers RM is asking for back. AM could potentially use this to decide which containers to kill. That can be future enhancement though.

I think this looks good other then @sryza comments.

Thanks all for reviewing !
@sryza Addressed your comment in the latest patch.
@tgravescs Yes, one use case on top of my mind is try to avoid preempting containers
which has RDD's cached. However, I believe the current implementation in the scheduler
doesn't take inputs from AM for preemption and that the list of containers in PreemptionMessage
is more of a notification to AM, no ?

Yeah I'm sure it would require more plumbing hence a future enhancement if we decide its useful.
