------------------------------------
Shravan, with you patch, load followed by dump works. However, describe still
dies with the following stack:

> Load expects to be connected to another operator and when it is not,an
> exception is raised. Two scripts that cause this behavior
> grunt> B = load 'foo' USING PigStorage() AS (s:chararray);
> grunt> describe B;
> grunt> B = load 'foo' USING PigStorage() AS (s:chararray);
> grunt> dump B;
