Pengcheng Xiong created HIVE-10479:
--------------------------------------

             Summary: Empty tabAlias in columnInfo which triggers PPD
                 Key: HIVE-10479
                 URL: https://issues.apache.org/jira/browse/HIVE-10479
             Project: Hive
          Issue Type: Sub-task
            Reporter: Pengcheng Xiong
            Assignee: Laljo John Pullokkaran


in ql/src/java/org/apache/hadoop/hive/ql/ppd/OpProcFactory.java, line 477, when aliases contains
empty string "" and key is an empty string "" too, it assumes that aliases contains key. This
will trigger incorrect PPD. To reproduce it, apply the HIVE-10455 and run cbo_subq_notin.q.
