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.
