Ashutosh Chauhan commented on HIVE-16996:
-----------------------------------------
Yeah we should do it in 2 steps. First for hll udaf and metastore changes
later.
Also, instead of adding new udaf you can overload existing compute_stats() udaf
so that we can reuse logic of other stats of the udaf.
> Add HLL as an alternative to FM sketch to compute stats
