> PIG Join fails while doing a filter on joined data
> Here are the steps to reproduce it:
> -bash-3.1$ pig -latest -x local
> grunt> a = load 'first.dat' using PigStorage('\u0001') as (f1:int,
> f2:chararray);
> grunt> DUMP a;
> (1,A)
> (2,B)
> (3,C)
> (4,D)
> grunt> b = load 'second.dat' using PigStorage() as (f3:chararray);
> grunt> DUMP b;
> (A)
> (D)
> (E)
> grunt> c = join a by f2 LEFT OUTER, b by f3;
> grunt> DUMP c;
> (1,A,A)
> (2,B,)
> (3,C,)
> (4,D,D)
> grunt> describe c;
> c: {a::f1: int,a::f2: chararray,b::f3: chararray}
> grunt> d = filter c by (f3 is null or f3 =='');
> grunt> dump d;

> 2010-03-03 15:00:37,130 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
> 1002: Unable to store alias d
> This one is failing too:
> grunt> d = filter c by (b::f3 is null or b::f3 =='');
> or this one not returning results as expected:
> grunt> d = foreach c generate f1 as f1, f2 as f2, f3 as f3;
> grunt> e = filter d by (f3 is null or f3 =='');
> grunt> DUMP e;
> (1,A,)
> (2,B,)
> (3,C,)
> (4,D,)
> while the expected result is
> (2,B,)
> (3,C,)
