Aihua Xu commented on HIVE-15074:
---------------------------------

> For some unknown reason, we see customer's HMS can not start because there are multiple
entries in their HMS VERSION table. Schematool should provide a way to validate the HMS db
and provide warning and fix options for this kind of issues.
