Reading in map data seems broken
--------------------------------

                 Key: PIG-1016
                 URL: https://issues.apache.org/jira/browse/PIG-1016
             Project: Pig
          Issue Type: Improvement
          Components: data
    Affects Versions: 0.4.0
            Reporter: hc busy


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.
