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

             Summary: Error in semantic analysis:Invalid Table Alias
                 Key: HIVE-3233
                 URL: https://issues.apache.org/jira/browse/HIVE-3233
             Project: Hive
          Issue Type: Bug
            Reporter: Raihan Jamal
            Priority: Minor


When I am trying to do this query I always get Semantic Analysis error-

hive> SELECT COUNT(*) FROM DW_CHECKOUT_TRANS JOIN PDS_ATTRIBUTE_DATA_REALTIME ON (DW_CHECKOUT_TRANS.BUYER_ID
= PDS_ATTRIBUTE_DATA_REALTIME.UID);
    FAILED: Error in semantic analysis: line 1:76 Invalid Table Alias DW_CHECKOUT_TRANS

But when I add table alias name infront of Table then it starts working? why is it so? Below
query works fine.

SELECT COUNT(*) FROM DW_CHECKOUT_TRANS CO JOIN PDS_ATTRIBUTE_DATA_REALTIME PDS ON (CO.BUYER_ID
= PDS.UID);
