Error with Pig (CDH4.0.0)
Hi everyone.. We just upgraded to CDH4.0.0 and are seeing a very weird issue with Pig.. Everytime I try to run a LOAD command, it dies with the following exception:

ERROR 2998: Unhandled internal error. name

java.lang.NoSuchFieldError: name

The same script/command worked fine with CDH3U3.. Did any APIs change? Or is this a bug?
