    Description

      Self join does not produce right results in case of null after PIG-4495 which writes multiple inputs into same tez input. Need the https://issues.apache.org/jira/secure/attachment/12628162/PIG-3761-1.patch fix of PIG-3761 to handle that by comparing indexes in the raw comparators.
