Subject [jira] [Created] (ACCUMULO-3182) WAL repeatedly failed recovery due to NPE in IT
Date Mon, 29 Sep 2014 05:25:33 GMT
Josh Elser created ACCUMULO-3182:
------------------------------------

             Summary: WAL repeatedly failed recovery due to NPE in IT
                 Key: ACCUMULO-3182
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3182
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 1.7.0


Haven't ever seen this one before. A replication IT failed -- looking into it, it was because
the tserver that came up (after killing the original) failed to complete recovery. The below
happened a few times before the test ultimately timed out.
