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

Konstantinos Karanasos created YARN-2883:
--------------------------------------------

             Summary: Queuing of container requests in the NM
                 Key: YARN-2883
                 URL: https://issues.apache.org/jira/browse/YARN-2883
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Konstantinos Karanasos


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.
