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