The hive directory isn't for installing new instances of HMS, since the HMS
can't use Hive itself as its database. It's for the information schema
support. So when I moved the HMS schemas over into standalone-metastore I
didn't move the hive directory, as it served a different purpose. I agree
it would be better to make that clear in the source tree.
