--------------------------------------------
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.
