Boaz Ben-Zvi created DRILL-5665: ----------------------------------- Summary: planner.force_2phase.aggr Set to TRUE for HashAgg may cause wrong results for VARIANCE and STD_DEV Key: DRILL-5665 URL: https://issues.apache.org/jira/browse/DRILL-5665 Project: Apache Drill Issue Type: Bug Components: Execution - Relational Operators Affects Versions: 1.11.0 Reporter: Boaz Ben-Zvi Assignee: Boaz Ben-Zvi Fix For: 1.11.0
*planner.force_2phase.aggr* was added for testing the hash 2-phase spill to disk aggregation implementation. However, if it is set to true, stream aggregate will run in two phase too and return wrong results for some functions such as variance() and std_dev(). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
