Map-reduce task does not produce correct results when -reducer NONE is specified through streaming

          Details

          • Type: Bug
          • Status: Closed
          • Priority: Major
          • Resolution: Fixed
          • Affects Version/s: None
          • Fix Version/s: 0.9.0
          • Component/s: None
          • Labels:
            None

            Description

            a) a file is create for the output instead of a directory.
            b) there is no way to understand what is going on from the client output

            I can produce an example for you, if you like – but the behavior is consistent, so $HSTREAM -mapper /bin/cat -reducer NONE should show the problem
