BasicTypeSorterBase.compare calls progress on each compare
----------------------------------------------------------

                 Key: HADOOP-2284
                 URL: https://issues.apache.org/jira/browse/HADOOP-2284
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
            Reporter: Owen O'Malley
            Assignee: Devaraj Das
             Fix For: 0.16.0


The inner loop of the sort is calling progress on each compare. I think it would make more sense to call progress in the sort rather than the compare or at most every 10000 compares. In the performance numbers, the call to progress as part of the sort are consuming 12% of the total cpu time when running word count under the local runner.
