Carl Steinbach commented on HIVE-259:
-------------------------------------
This would be a very useful function to have.
For the sake of completeness (and without much additional effort) it would be
nice to provide both PERCENTILE_DISC and PERCENTILE_CONT.
PERCENTILE_CONT:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/functions110.htm
PERCENTILE_DISC:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/functions111.htm
> Add PERCENTILE aggregate function
