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

             Summary: Query with unsupported windows function containing "AS" blocks correct error message
                 Key: DRILL-3326
                 URL: https://issues.apache.org/jira/browse/DRILL-3326
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.1.0
            Reporter: Krystal
            Assignee: Sean Hsuan-Yi Chu


The following query contains "AS"  using un-supported function first_value gives incorrect error:

select FIRST_VALUE(voter_id) OVER (PARTITION BY age ORDER BY contributions ROWS BETWEEN CURRENT ROW AND 1 FOLLOWING) as t from voter_hive;
Error: SYSTEM ERROR: org.apache.drill.exec.exception.SchemaChangeException: Failure while materializing expression. 
Error in expression at index -1.  Error: Missing function implementation: [first_value(INT-OPTIONAL)].  Full expression: --UNKNOWN EXPRESSION--.

After I remove the "AS" keyword, the correct error message is displayed:
select FIRST_VALUE(voter_id) OVER (PARTITION BY age ORDER BY contributions ROWS BETWEEN CURRENT ROW AND 1 FOLLOWING) from voter_hive;
Error: UNSUPPORTED_OPERATION ERROR: The window function FIRST_VALUE is not supported
