Subject [jira] [Created] (ACCUMULO-2095) Shard randomwalk test fails w/ multiple namnodes
Date Tue, 24 Dec 2013 22:55:50 GMT
Keith Turner created ACCUMULO-2095:
--------------------------------------

             Summary: Shard randomwalk test fails w/ multiple namnodes
                 Key: ACCUMULO-2095
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2095
             Project: Accumulo
          Issue Type: Bug
            Reporter: Keith Turner
             Fix For: 1.6.0


Was running random walk w/ two namenodes configured for Accumulo and saw the following error.
  I think this is just a bug in the test code not handling multiple namenodes.
