-----------------------------------

             Summary: To forbid stderr and stdout for MapReduce job
                 Key: MAPREDUCE-6220
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6220

          Issue Type: Improvement
          Components: mrv2
    Affects Versions: 2.6.0
            Reporter: Yang Hao


System.out and System.error is a ugly way to print log, and many times it would do harm to Hadoop cluster. So an alternative is to forbid it
