[jira] Created: (MAPREDUCE-1484) Framework should not sort the input splits

Framework should not sort the input splits
------------------------------------------

                 Key: MAPREDUCE-1484
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1484
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Owen O'Malley


Currently the framework sorts the input splits by size before the job is submitted. This makes it very difficult to run map only jobs that transform the input because the assignment of input names to output names isn't obvious. We fixed this once in HADOOP-1440, but the fix was broken so it was rolled back.
