Pengcheng Xiong commented on HIVE-16996:
----------------------------------------
[~ashutoshc] and [~hagleitn], it seems that if we shift from FM to HLL, we will
already have lots of plan changes. Let alone the aggregation of partition
stats. Do you want to try it in a single step (i.e., replace FM with HLL and do
the aggr) or split into 2 steps? Thanks.
> Add HLL as an alternative to FM sketch to compute stats
