[jira] [Updated] (YARN-2883) Queuing of container requests in the NM

["Konstantinos Karanasos (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-2883?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Konstantinos Karanasos updated YARN-2883:
-----------------------------------------
    Attachment: YARN-2883-trunk.009.patch

I am attaching a new version of the patch, in which I have moved the queuing of containers to the {{QueuingContainerManagerImpl}}.
I purposely left in the {{QueuingContainersManagerImpl}} the part that had to do with the utilization of the allocated containers.
I also added all the needed synchronization.

[~kasha] and [~asuresh], please give it a look and let me know how it looks.

> 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.
