             Summary: NodeManager should shutdown when PublicLocalizer is 
exiting.
                 Key: YARN-11746
                 URL: https://issues.apache.org/jira/browse/YARN-11746
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Chenyu Zheng
            Assignee: Chenyu Zheng


I found that PublicLocalizer is exiting, because of the /tmp directory was 
deleted by mistake, then throw NPE, then causing spark job to be stuck.

YARN-9968 have resolve the NPE problem. For me, I think when the `Public 
Localizer` thread exits, the NM should be shut down, because there is no point 
in keeping an abnormal NM running.
