Subject [jira] [Created] (HDFS-5653) Log namenode hostname in various exceptions being thrown in a HA setup

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

             Summary: Log namenode hostname in various exceptions being thrown in a HA setup
                 Key: HDFS-5653
                 URL: https://issues.apache.org/jira/browse/HDFS-5653
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: ha
    Affects Versions: 2.2.0
            Reporter: Arpit Gupta


In a HA setup any time we see an exception such as safemode or namenode in standby etc we
dont know which namenode it came from. The user has to go to the logs of the namenode and
determine which one was active and/or standby around the same time.
I think it would help with debugging if any such exceptions could include the namenode hostname
so the user could know exactly which namenode served the request.
