Jason Lowe created YARN-4930: -------------------------------- Summary: Convenience command to perform a work-preserving stop of the nodemanager Key: YARN-4930 URL: https://issues.apache.org/jira/browse/YARN-4930 Project: Hadoop YARN Issue Type: Improvement Reporter: Jason Lowe Priority: Minor
When the nodemanager is not under supervision (yarn.nodemanager.recovery.supervised=false) there may be cases where an admin wants to perform a work-preserving maintenance of the node but the nodemanager stop CLI command will cause the NM to cleanup containers. There should be a CLI command that shuts down the NM while preserving local filesystem and container state to allow a subsequent nodemanager start to recover containers. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
