[jira] [Created] (HIVE-12261) schematool version info exit status should depend on compatibility, not equality

Thejas M Nair created HIVE-12261:
------------------------------------

             Summary: schematool version info exit status should depend on compatibility, not equality
                 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


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.
