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.
> Job with last_value() function keep running forever.
