------------------------------

             Summary: Add health checker to ResourceManager
                 Key: YARN-7035
                 URL: https://issues.apache.org/jira/browse/YARN-7035
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: sandflee


RM may becomes unhealthy but still alive,  for example scheduling thread exit, dead lock happens.
 seems useful to add a healthy checker service, if check failed, let RM exit
