             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
