> 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.
