> Specifically when the versions are the same, we still try and record a new version:
> {code}
>       // metastore schema version is different than Hive distribution needs
>       if (strictValidation) {
>         if (!schemaVer.equalsIgnoreCase(MetaStoreSchemaInfo.getHiveSchemaVersion())) {
>           throw new MetaException("Hive Schema version "
>               + MetaStoreSchemaInfo.getHiveSchemaVersion() +
>               " does not match metastore's schema version " + schemaVer +
>               " Metastore is not upgraded or corrupt");
>         } else {
>           LOG.warn("Metastore version was " + schemaVer + " " +
>               HiveConf.ConfVars.METASTORE_SCHEMA_VERIFICATION.toString() +
>               " is not enabled so recording the new schema version " +
>               MetaStoreSchemaInfo.getHiveSchemaVersion());
>           setMetaStoreSchemaVersion(MetaStoreSchemaInfo.getHiveSchemaVersion(),
>               "Set by MetaStore");
>         }
> {code}
