----------------------------------------

             Summary: Incomplete implementation in pig
                 Key: PIG-2758
                 URL: https://issues.apache.org/jira/browse/PIG-2758
             Project: Pig
          Issue Type: Bug
         Environment: All env
            Reporter: Mridul Muralidharan


Support for Map's is not consistent in the builtin evalfunc/impl. There might 
be other inconsistencies too (like BIGCHARARRAY, but I have not investigated).

For example: search for Long.class or Long.TYPE - this gives us the list of 
classes/usecases where "Map" is not supported the same way .. Invoker, 
MonitoredUDFExecutor.

This is NOT a principled way to find all instances of this sort of buggy 
behavior - someone with better knowledge of pig internals (DataType's, other 
langs, checks, etc) can do a better job.
