Karthik Kambatla commented on YARN-2883:
----------------------------------------
The latest patch (YARN-2883.013.patch) looks mostly good to me, barring some
unaddressed comments from my previous review - visibility of methods in
ContainersMonitorImpl and the config itself. As I said, for the config, I am
comfortable filing a follow-up. And, yeah, the findbugs.

> We propose to add a queue in each NM, where queueable container requests can
> be held.
> Based on the available resources in the node and the containers in the queue,
> the NM will decide when to allow the execution of a queued container.
> In order to ensure the instantaneous start of a guaranteed-start container,
> the NM may decide to pre-empt/kill running queueable containers.
