Ray Chiang created YARN-5644: -------------------------------- Summary: Define exit code for allowing NodeManager health script to mar Key: YARN-5644 URL: https://issues.apache.org/jira/browse/YARN-5644 Project: Hadoop YARN Issue Type: Sub-task Components: nodemanager Affects Versions: 3.0.0-alpha2 Reporter: Ray Chiang Assignee: Yufei Gu
Done as a alternate design to YARN-5567. Define a specific exit code for the health checker script (property yarn.nodemanager.health-checker.script.path) that allows the node to be blacklisted. As discussed in the latter part of YARN-5567, the current design requirements are: # Ignore all exit codes from the script ## _except_ the newly defined error code which will mark the NodeManager as UNHEALTHY ## This allows any syntax or functional errors in the script to be ignored # Upon failure (or multiple recorded failures): ## Store the status in the metrics2 state on the NodeManager ## Allow the RM to blacklist the NM or allow the jobs to drain -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
