Konstantinos Karanasos updated YARN-2883:
-----------------------------------------
Attachment: YARN-2883-trunk.005.patch
Adding updated patch, after addressing [~chris.douglas]'s comments.
Also addressed [~kasha]'s first comments.
I added a new JIRA (YARN-4861), so that we address the comment related to the
ExitStatus of a killed OPPORTUNISTIC container.
Moreover, I did not address the comment about bounding the queue size, as this
should be done in a new JIRA too.

> 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.
