This issue has been fixed in PIG-655
(https://issues.apache.org/jira/browse/PIG-665). Latest trunk has the
fix.

Thanks,

I am getting this exception running pig task:

2009-02-25 01:11:44,167 [main] ERROR
org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.Launcher
- Error message from task (map)

        at org.apache.hadoop.mapred.Child.main(Child.java:155)

Corresponding source line is:

            key.setIndex(index);

I am running trunk version (maybe not most recent, but after types
branch merge) with patches applied to run with Hadoop 19.

What is causing this exception?

Sincerely,
Vadim
