Hong Zhiguo created YARN-3965:
---------------------------------

             Summary: Add starup timestamp for nodemanager
                 Key: YARN-3965
                 URL: https://issues.apache.org/jira/browse/YARN-3965
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
            Reporter: Hong Zhiguo
            Priority: Minor


We have startup timestamp for RM already, but don't for NM.
Sometimes cluster operator modified configuration of all nodes and kicked off command to restart all NMs.  He found out it's hard for him to check whether all NMs are restarted.  Actually there's always some NMs didn't restart as he expected, which leads to some error later due to inconsistent configuration.

If we have startup timestamp for NM,  the operator could easily fetch it via NM webservice and find out which NM didn't restart, and take mannaul action for it.
