> 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.
