-------------------------------------

             Summary: RegExFilter set when not needed by AccumuloInputFormst
                 Key: ACCUMULO-825
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-825
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.4.0, 1.4.1
            Reporter: Keith Turner
            Priority: Trivial


I was running continuous verify test for the 1.4.2 release.  I ran listscans and noticed that
the RegExFitler was present.

No regexes were set for the map reduce job, so the filter did not need to be set.  I do not
think this impacted performance in a noticeable way.
