Jerome Boulon commented on HIVE-259:
------------------------------------
Didn't know that we can use an Hash on the state Object ...
Is there any limitation on what can be used on the state object or can we use
any java Object?
Also how is the state serialized between Map and Reduce?
> Add PERCENTILE aggregate function
