Subject [jira] [Created] (ACCUMULO-1625) Accumulo shouldn't reuse filenames for .rf files
Date Wed, 31 Jul 2013 15:25:48 GMT
Sean Hickey created ACCUMULO-1625:
-------------------------------------

             Summary: Accumulo shouldn't reuse filenames for .rf files
                 Key: ACCUMULO-1625
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1625
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.6.0
            Reporter: Sean Hickey


While running RandomWalk, I ran into an error where an .rf file couldn't be found. The logs
point to it being deleted under one table and then another table tries to reference the same
filename. Here's one example from the accumulo logs (the randomwalk logs just say there was
a server error).
