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

             Summary: Exit early out of HashJoinBatch if build side is empty  
                 Key: DRILL-2580
                 URL: https://issues.apache.org/jira/browse/DRILL-2580
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Relational Operators

            Assignee: Mehant Baid
             Fix For: 0.9.0
         Attachments: DRILL-2580.patch

Currently in HashJoinBatch if the build side is empty we still seem to be going through every record in the probe side. If we don't have an inner join we should be exiting early.
