            Description

            We just upgraded to CDH4.2.0, but now I get this error when doing a relatively simple pig query.

            All Google gives me is this

            https://issues.apache.org/jira/browse/MAPREDUCE-5034

            so is it possible CDH4.2.0 includes the "previous version of the patch" they're referring to?
