Ashutosh Chauhan commented on HIVE-19598: ----------------------------------------- Changes in packaging/pom.xml will bundle this jar with 3.0 distro. But since it declares dependency on hive-2.3.3 I suspect it will package hive-2.3 jars as well which may be trouble. I think all dependencies of this module should be excluded from packaging and should only contain this jar only. > 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 > Priority: Critical > Attachments: HIVE-19598.02.patch, HIVE-19598.05.patch > > > 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)
