Viraj Bhat reopened PIG-1194:
-----------------------------
Hi Richard,
I ran the script attached on the ticket and found out that the map tasks fails
with the following error:
org.apache.pig.backend.executionengine.ExecException: ERROR 2055: Received
Error while processing the map plan. at
org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.PigMapBase.runPipeline(PigMapBase.java:281)

I am using the latest pig.jar without hadoop.
