Eugene Koifman created HIVE-19598: ------------------------------------- Summary: Acid V1 to V2 upgrade Key: HIVE-19598 URL: https://issues.apache.org/jira/browse/HIVE-19598 Project: Hive Issue Type: Bug Components: Transactions Affects Versions: 3.0.0 Reporter: Eugene Koifman Assignee: Eugene Koifman
The on-disk layout for full acid (transactional) tables has changed 3.0. Any transactional table that has any update/delete events in any deltas that have not been Major compacted, must go through a Major compaction before upgrading to 3.0. No more update/delete/merge should be run after/during major compaction. Not doing so will result in data corruption/loss. Need to create a utility tool to help with this process. HIVE-19233 started this but it needs more work. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
