Karen Coppage created HIVE-24015: ------------------------------------ Summary: Disable query-based compaction on MR execution engine Key: HIVE-24015 URL: https://issues.apache.org/jira/browse/HIVE-24015 Project: Hive Issue Type: Task Reporter: Karen Coppage Assignee: Karen Coppage
Major compaction can be run when the execution engine is MR. This can cause data loss a la HIVE-23703 (the fix for data loss when the execution engine is MR was reverted by HIVE-23763). Currently minor compaction can only be run when the execution engine is Tez, otherwise it falls back to MR (non-query-based) compaction. We should extend this functionality to major compaction as well. -- This message was sent by Atlassian Jira (v8.3.4#803005)
