Nice spot on, but it seems that's not the problem...I am able to run
this successfully on pig 0.9 and 0.10 any ideas how further I can debug the
problem?

I also double checked all the variables, seems to be fine:
PIG_CLASSPATH=/opt/hcat/share/hcatalog/hcatalog-0.4.0.jar:/usr/lib/hive/conf:/usr/lib/hadoop-0.20/conf

/usr/lib/hive/conf and /usr/lib/hadoop-0.20/conf also exist.

Thanks.
