------------------------------------
Shravan,
I just tried again and here is my grunt session:
grunt> B = load 'foo' USING PigStorage() AS (s:chararray);
grunt> describe B;
{s: chararray}
grunt> C = load 'foo' USING PigStorage() AS (s:chararray);
grunt> dump C;

> exception is raised. Two scripts that cause this behavior
