Eugene Koifman commented on HIVE-21254: --------------------------------------- this seems dangerous. If the tools misses any tables that were actually Acid and need compacting, all the user sees is a WARN in the log which is easy to miss. And try to use Acid V1 table from Hive 3 will result in data loss (and perhaps corruption) > Pre-upgrade tool should handle exceptions and skip db/tables > ------------------------------------------------------------ > > Key: HIVE-21254 > URL: https://issues.apache.org/jira/browse/HIVE-21254 > Project: Hive > Issue Type: Bug > Components: Transactions > Affects Versions: 4.0.0 > Reporter: Prasanth Jayachandran > Assignee: Prasanth Jayachandran > Priority: Major > Attachments: HIVE-21254.1.patch, HIVE-21254.2.patch, > HIVE-21254.3.patch, HIVE-21254.4.patch > > > When exceptions like AccessControlException is thrown, pre-upgrade tool > fails.
