> Components: contrib/streaming
> Affects Versions: 0.14.0
> Environment: fedora core 7 linux on x86
> Reporter: John Heidemann
> Assignee: John Heidemann
> Priority: Minor
> Fix For: 0.14.0

>
> 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.
