> Key: HIVE-12261
> URL: https://issues.apache.org/jira/browse/HIVE-12261
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 1.3.0, 2.0.0
> Reporter: Thejas M Nair
> Assignee: Thejas M Nair
> Attachments: HIVE-12261-branch-1.0.0.patch, HIVE-12261-branch-1.patch

>
> Newer versions of metastore schema are compatible with older versions of
> hive, as only new tables or columns are added with additional information.
> HIVE-11613 added a check in hive schematool -info command to see if schema
> version is equal.
> However, the state where db schema version is ahead of hive software version
> is often seen when a 'rolling upgrade' or 'rolling downgrade' is happening.
> This is a state where hive is functional and returning non zero status for it
> is misleading.
