Subject [jira] [Created] (YARN-3712) ContainersLauncher: handle event CLEANUP_CONTAINER asynchronously
Date Tue, 26 May 2015 05:05:17 GMT
Jun Gong created YARN-3712:
------------------------------

             Summary: ContainersLauncher: handle event CLEANUP_CONTAINER asynchronously
                 Key: YARN-3712
                 URL: https://issues.apache.org/jira/browse/YARN-3712
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
            Reporter: Jun Gong
            Assignee: Jun Gong


It will save some time by handling event CLEANUP_CONTAINER asynchronously. 

This improvement will be useful for cases that cleaning up container cost a little long time(e.g.
for our case: we are running Docker container on NM, it will take above 1 seconds to clean
up one docker container.  ) and many containers to clean up(e.g. NM need clean up all running
containers when NM shutdown).
