Did you use the patch submitted as part of PIG-573
(https://issues.apache.org/jira/browse/PIG-573)

I have recently upgraded to Hadoop-0.19.1 (from 0.19.0). The pig task
which used to work previously
on it, does not work anymore, giving me cryptic error:

ERROR 2998: Unhandled internal error. depending job 0 with jobID
execute8 failed. depending job 0 with jobID execute7 failed. depending
job 2 with jobID execute6 failed. depending job 0 with jobID execute5

Anybody else is using Hadoop-0.19.1 with PIG? Any problems?
