Review Comment:
+1 to Szehon's point. I think the original tableExists returned true for
metadata tables too. I doesn't seem to be covered here.

Review Comment:
Unrelated, but this test also verifies that there is an existing table
remaining from the previous test. All these tests would be much simpler if they
cleaned up after themselves.

Review Comment:
I think the behaviour on this area is unchanged with this PR. This function
returned false when there was a Hive table with the same name and does so with
this change too.
