      Description

      For the following command, it will sleep 5 seconds for mapper and finish the reduce immediately

      hadoop jar tez-mapreduce-examples/target/tez-mapreduce-examples-0.5.0-SNAPSHOT.jar mrrsleep -m 2 -r 2  -mt 5000 -rt 5000
      

      While for the following command it will sleep 5 seconds for mapper and sleep 5 seconds for reducer

      hadoop jar tez-mapreduce-examples/target/tez-mapreduce-examples-0.5.0-SNAPSHOT.jar mrrsleep -m 2 -r 2 -irs 0 -mt 5000 -rt 5000
      

      The behavior do not looks correct to me. If it is expected, the behavior of MRRSleepJob should be specified in the javadoc at least, otherwise it will confuse users.
