Abhishek Girish commented on DRILL-3337:
----------------------------------------

Similarly, function PERCENT_RANK also fails:

{code:sql}
SELECT c.c_first_name, c.c_last_name, PERCENT_RANK() OVER (PARTITION BY s.ss_customer_sk ORDER BY s.ss_customer_sk) FROM customer c, store_sales s WHERE c.c_customer_sk = s.ss_customer_sk GROUP BY c.c_first_name, c.c_last_name, s.ss_quantity, s.ss_customer_sk ORDER BY 1, 2 LIMIT 20;
Error: SYSTEM ERROR: org.apache.drill.exec.exception.SchemaChangeException: Failure while materializing expression. 
Error in expression at index 0.  Error: Missing function implementation: [percent_rank(INT-REQUIRED)].  Full expression: null.

Fragment 5:5
