      Description

      As described in
      http://mail-archives.apache.org/mod_mbox/lucene-hadoop-user/200707.mbox/browser

      bugs in the subprocesses started by hadoop streaming currently result in the less-than-intuitive "broken pipe" error. This patch modifies streaming to indicate when the subprocess fails with "subprocess exited with error code x" for non-successful error codes.

      A patch will follow.
