Description

If you have ( A1=pigstatement) and you have (A2= pigstatement), A1will pass and A2 will fail.
Here is an example using load:

The first statement works, the second statement results in a stack trace. The only difference is the space beween A= and load.

grunt> A = load 'studenttab10k' using PigStorage() as (name, age, gpa );
grunt> A=load 'studenttab10k' using PigStorage() as ( name, age, gpa );
