Subject [jira] [Updated] (YARN-2883) Queuing of container requests in the NM
Date Thu, 24 Mar 2016 02:19:25 GMT

     [ 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.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.
