join assumes all columns are string - pass the objectinspector from execreducer and use that
Cleanup operator initialization
1. The patch adds ObjectInspector to Operator.initialize, but that parameter is only set for JoinOperator. I guess the intention is to leave the rest of the work to HIVE-405?
2. Utility.hashCode() is not very efficient. I think we should do a "switch" based on the Category and PrimitiveCategory of the object.
Will commit if test passes.
