[jira] [Created] (YARN-5688) Make allocation of opportunistic containers asynchronous

Konstantinos Karanasos created YARN-5688:
--------------------------------------------

             Summary: Make allocation of opportunistic containers asynchronous
                 Key: YARN-5688
                 URL: https://issues.apache.org/jira/browse/YARN-5688
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Konstantinos Karanasos


In the current implementation of the {{OpportunisticContainerAllocatorAMService}}, we synchronously perform the allocation of opportunistic containers. This results in "blocking" the service at the RM when scheduling the opportunistic containers.
The {{OpportunisticContainerAllocator}} should instead asynchronously run as a separate thread.
