> 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.
