> 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
