                 Key: YARN-8823
                 URL: https://issues.apache.org/jira/browse/YARN-8823
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Zhankun Tang


We have GPU resource discovered when the NM bootstrap but not updated through 
later heatbeat with RM. There should be a monitoring mechanism to check GPU 
healthy status from time to time and also the corresponding handling.
