                 Key: MAPREDUCE-2350
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2350
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Ahmed Radwan


LocalJobRunner uses the "mapred.output.committer.class" configuration property to retrieve the output committer for the job, which can be different from the Output Committer returned from OutputFormat.getOutputCommitter(TaskAttemptContext context). So, two different output committers can be used in the same job.

See line 324 in org.apache.hadoop.mapred.LocalJobRunner: OutputCommitter outputCommitter = job.getOutputCommitter();

Need to modify this behavior to check if the new or the old API is used, and then return the correct output committer.
