hc busy commented on PIG-1016:
------------------------------
I skimed PIG-880. Here is a simplified version of what I might need to do:
bash% cat map.dat
[a#2,b#'d',c#(1,2,3)]
[a#1,b#'a',c#(1,2,3)]
[a#3,b#'c',c#(1,2,3)]
bash% PIG
grunt>A= load 'map.dat' as (data:map[]);
grunt>B= foreach A generate (int)(data#'a'),
(chararray)(data#'b'),(tuple())(data#'c');
grunt>C= order B by $0;
grunt>dump C;
(1,'a',(1,2,3))
(2,'d',(1,2,3))
(3,'c',(1,2,3))
grunt>D= order B by $1;
grunt>dump D;
(1,'a',(1,2,3))
(3,'c',(1,2,3))
(2,'d',(1,2,3))
> Reading in map data seems broken

> Hi, I'm trying to load a map that has a tuple for value. The read fails in
> 0.4.0 because of a misconfiguration in the parser. Where as in almost all
> documentation it is stated that value of the map can be any time.
> I've attached a patch that allows us to read in complex objects as value as
> documented. I've done simple verification of loading in maps with tuple/map
> values and writing them back out using LOAD and STORE. All seems to work fine.
