Subject [jira] [Resolved] (ACCUMULO-825) RegExFilter set when not needed by AccumuloInputFormst
Date Fri, 19 Oct 2012 17:52:12 GMT

]

Keith Turner resolved ACCUMULO-825.
-----------------------------------

    Resolution: Won't Fix

This problem does not exist in 1.5.  I do not think its causing any problems in 1.4. So it
can probably be left as-is.

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.
