Harish Butani commented on HIVE-4192:
-------------------------------------

Yes in our implementation we disallow Window Frames on rank, dense_rank, cume_dist, percent_rank, lead and lag. Didn't make sense to allow a Window Frame on these. This is documented in Jira 4197. Should be fixed/resolved by Jira 4197.
