Subject [jira] [Created] (YARN-1292) De-link container life cycle from the process it runs
Date Thu, 10 Oct 2013 22:28:43 GMT
Bikas Saha created YARN-1292:
--------------------------------

             Summary: De-link container life cycle from the process it runs
                 Key: YARN-1292
                 URL: https://issues.apache.org/jira/browse/YARN-1292
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 2.1.1-beta
            Reporter: Bikas Saha


Currently, a container is considered done when its OS process exits. This makes it cumbersome
for apps to be able to reuse containers for different processes. Long running daemons may
want to run in the same containers as the previous versions. So eg. is an hbase region server
crashes/upgraded it would want to restart in the same container where everything it needs
would already be warm and ready.
