Daniel Dai commented on PIG-1016:
---------------------------------
I think the problem is in current TextDataParser, map is defined as
String#String, and string exclude special characters such as "(", ")", ",", so
busy has no way to generate a tuple in the value field of the map. The approach
busy took looks valid to me.
> 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.
