Subject [jira] [Created] (ACCUMULO-2693) Tablet Server Failed to "add Datanode"
Date Thu, 17 Apr 2014 22:21:15 GMT
Mike Drob created ACCUMULO-2693:

             Summary: Tablet Server Failed to "add Datanode"
                 Key: ACCUMULO-2693
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
    Affects Versions: 1.6.0
         Environment: 1.6.0 RC2, starting CI
            Reporter: Mike Drob

Right when starting CI, I got the following error message on the monitor, and potentially
related DEBUG statements in the tserver log.

2014-04-17 15:04:17,940 [log.DfsLogger] ERROR: Failed to add a datanode.

This error seems like it was probably completely harmless, so it should be a warn or info.
