[jira] [Created] (HIVE-22201) ConvertJoinMapJoin#checkShuffleSizeForLargeTable throws ArrayIndexOutOfBoundsException if no big table is selected

Himanshu Mishra created HIVE-22201:
--------------------------------------

             Summary: ConvertJoinMapJoin#checkShuffleSizeForLargeTable throws ArrayIndexOutOfBoundsException if no big table is selected
                 Key: HIVE-22201
                 URL: https://issues.apache.org/jira/browse/HIVE-22201
             Project: Hive
          Issue Type: Bug
            Reporter: Himanshu Mishra


In case when {{bigTableCandidateSet}} is empty e.g. full outer join, we end up calling {{checkShuffleSizeForLargeTable}} with {{bigTablePosition}} as -1, resulting in {{ArrayIndexOutOfBoundsException}}.

Also, should we return as soon as we see {{bigTableCandidateSet}} is empty ?
