liyunzhang_intel created PIG-5197:
-------------------------------------

             Summary: Replace IndexedKey with PigNullableWritable in spark branch
                 Key: PIG-5197
                 URL: https://issues.apache.org/jira/browse/PIG-5197
             Project: Pig
          Issue Type: Sub-task
            Reporter: liyunzhang_intel


The function of IndexedKey and PigNullableWritable is similar. 
The difference between these two is  IndexedKey contains Index,key while PigNullableWritable contains index,key,value.
Besides,the comparators for PigNullableWritable have lot of conditions for the different data types taken care of and IndexedKey can miss some of that. We can try to replace IndexedKey with PigNullableWritable.
