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

             Summary: NodeManager should go unhealthy when state store throws DBException

                 Key: YARN-7585
                 URL: https://issues.apache.org/jira/browse/YARN-7585
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Wilfred Spiegelenburg
            Assignee: Wilfred Spiegelenburg


If work preserving recover is enabled the NM will not start up if the state store does not
initialise. However if the state store becomes unavailable after that for any reason the NM
will not go unhealthy. 
Since the state store is not available new containers can not be started any more and the
NM should become unhealthy:
