------------------------------------
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.
