--------------------------------
Summary: Distinguish between nodemanager shutdown for decommission
vs shutdown for restart
Key: YARN-1362
URL: https://issues.apache.org/jira/browse/YARN-1362
Project: Hadoop YARN
Issue Type: Sub-task
Components: nodemanager
Affects Versions: 2.3.0
Reporter: Jason Lowe
When a nodemanager shuts down it needs to determine if it is likely to be
restarted. If a restart is likely then it needs to preserve container
directories, logs, distributed cache entries, etc. If it is being shutdown
more permanently (e.g.: like a decommission) then the nodemanager should
cleanup directories and logs.
