> 1, 2, 3
> 4, 5, 6
> 7, 8, 9
> a = load '1.txt' using PigStorage(',') as (x:int, y:int, z:int);
> b = foreach a generate TOTUPLE(x, y) as t, z;
> c = group b by t;
> d = foreach c generate flatten(b);
> e = foreach d generate t;
> Describing d shows the schema as d: {b::t: (x: int,y: int),b::z: int}
> However, when dumping d the output is
> (1,3)
> (4,6)
> (7,9)
> Describing e shows the schema as e: {b::t: (x: int,y: int)}
> However, when dumping I got the following error:
> java.lang.ClassCastException: java.lang.Integer cannot be cast to
> org.apache.pig.data.Tuple
