ratnakar commented on HIVE-11189:
---------------------------------
When used with last_value(<col>, true), I am getting all values as "NULL", its
not working correctly.
> Add 'IGNORE NULLS' to FIRST_VALUE/LAST_VALUE
> --------------------------------------------

> Other RDBMS support the specification of 'IGNORE NULLS' over a paritition to
> skip NULL values for Analytic Functions. Example - Oracle's docs:

> Please consider adding this to Hive.
