Gopal V commented on HIVE-18722: -------------------------------- SUM(hash()) out of a Group-by query is not expected to be consistent (since JDK8), because it uses an iterator from a a HashMap If you're seeing different results with {{set hive.map.aggr=false}}, then it might be worth investigating. > Vectorization: Adding SUM(HASH(..)) to full query seems to produce flakey > results -- need to investiage > ------------------------------------------------------------------------------------------------------- > > Key: HIVE-18722 > URL: https://issues.apache.org/jira/browse/HIVE-18722 > Project: Hive > Issue Type: Bug > Components: Hive > Affects Versions: 3.0.0 > Reporter: Matt McCline > Assignee: Matt McCline > Priority: Critical > > When added to HIVE-18622 changes, the query results vary from laptop results > when run on Hive QA cluster.
