Replace the JobConf.setNumOfMapTasks with FileInputFormat.setMapInputSize(long)
-------------------------------------------------------------------------------

                 Key: HADOOP-1451
                 URL: https://issues.apache.org/jira/browse/HADOOP-1451
             Project: Hadoop
          Issue Type: Improvement
          Components: mapred
    Affects Versions: 0.12.3
            Reporter: Owen O'Malley
             Fix For: 0.14.0


It is confusing to users to set the number of mappers and have the system override it. It
would be far less confusing to remove JobConf.setNumMapTasks and FileInputFormat.setMinSplitSize
and have a single FileInputFormat.setMapInputSize(long) and simplify the logic around it.
