> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 0.20.205.0
> Reporter: Araceli Henley
> Attachments: MAPREDUCE-4278-2-branch1.patch,

> I cannot run two local mode jobs from Pig in parallel from the same gateway,
> this is a typical use case. If I re-run the tests sequentially, then the test
> pass. This seems to be a problem from Hadoop.
> Additionally, the pig harness, expects to be able to run
> Pig-version-undertest against Pig-version-stable from the same gateway.
> To replicate the error:
> I have two clusters running from the same gateway.
> If I run the Pig regression suites nightly.conf in local mode in paralell -
> once on each cluster. Conflicts in M/R local mode result in failures in the
> tests.
