          Components: grunt
    Affects Versions: types_branch
         Environment: Linux 2.6.9-55.ELsmp #1 SMP Fri Apr 20 16:36:54 EDT 2007

            Priority: Trivial
             Fix For: types_branch


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 );
