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 > ------------------------------------------------------- > > Key: HIVE-16996 > URL: https://issues.apache.org/jira/browse/HIVE-16996 > Project: Hive > Issue Type: Sub-task > Reporter: Pengcheng Xiong > Assignee: Pengcheng Xiong > Attachments: HIVE-16966.01.patch > > -- This message was sent by Atlassian JIRA (v6.4.14#64029)
