Mike Drob created ACCUMULO-2693:
-----------------------------------

             Summary: Tablet Server Failed to "add Datanode"
                 Key: ACCUMULO-2693
                 URL: https://issues.apache.org/jira/browse/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.

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