Allan Avendaño commented on PIG-2583:
-------------------------------------
I was working on this, but I found something particular if we show the last
definition for the alias, for example on this sequence:
A = load 'data/abs' using PigStorage('|') as (name:chararray, id1:int, id2:int,
id3:int);
D = group A by id1;
A = load 'data/abs' using PigStorage('|') as (name:chararray, x:int, y:int,
z:int);
With modifications on the patch that I attach, the following history is shown
(according to historical modifications on aliases):
D = group A by id1;
A = load 'data/abs' using PigStorage('|') as (name:chararray, x:int, y:int,
z:int);
But, D will work on previous schema of A, and not with the last definition. And
maybe, we are missing this other historical point of view.
