Subject [jira] [Created] (AMBARI-5806) /etc/hadoop/conf/dfs.exclude should be populated in SNN node too.
Date Mon, 19 May 2014 12:14:38 GMT
Andrew Onischuk created AMBARI-5806:

             Summary: /etc/hadoop/conf/dfs.exclude should be populated in SNN node too.
                 Key: AMBARI-5806
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.6.1

This is harmless. SNN can start up with an exception. We should fix it in
future release. (For now, I logged this to 1.6.0.)
