> Turns out malformed HMS database is pretty common phenomenon and MetastoreCacheInitializer.java is not really helpful in figuring out what's wrong. The result is failure in initializing MetastorePlugin.
> Adding simple stuff, like testing for returned null objects as opposed to waiting till dereferencing them produces NullPointerException would go a long way in making life easier.
