dump does not display of map of maps correctly
----------------------------------------------
Key: PIG-707
URL: https://issues.apache.org/jira/browse/PIG-707
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Pradeep Kamath
Priority: Minor
Fix For: types_branch
If a field in the output relation (which you are trying to dump) is a map whose
values are maps, dump does not display the inner map in the value in the
key#value format. It appears that the toString() of HashMap is being called
which displays the inner map as {key1 = value1, key2 = value2...} - this needs
to change to [key1#value,key2#vaule2...]
