>                 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.
