Rahul commented on HIVE-13205:
------------------------------

Hi,

I am running following query to fill all null with the last known value in the column:
Select price,time, id,last_value(price,true) over (partition by id order by time) as LatestPrice from table;

For few record, the query is running successfully. Buy for large number of records (2 Bn), the query keep running forever.
