      Streaming option -combiner allows any streaming command (not just Java class) to be a combiner.

      Description

      Streaming jobs are way slower than Java jobs for many reasons, but certainly stopping the shell-only programmer from using the combiner feature won't help. Right now, the streaming usage says:

      -mapper <cmd|JavaClassName> The streaming command to run
      -combiner <JavaClassName> Combiner has to be a Java class
      -reducer <cmd|JavaClassName> The streaming command to run
