[jira] [Created] (YARN-2887) AM policies for choosing type of containers

Konstantinos Karanasos created YARN-2887:
--------------------------------------------

             Summary: AM policies for choosing type of containers
                 Key: YARN-2887
                 URL: https://issues.apache.org/jira/browse/YARN-2887
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Konstantinos Karanasos


Each AM can employ policies that determine what type of container (guaranteed-start or queueable) should be requested for each task. 
An example policy may be to use only guaranteed-start or only queueable containers, or to randomly pick a percentage of the requests to be queueable, or to choose the container type based on the characteristics of the tasks.
