Review Comment:
In my understanding Preconditions are for checking some internal state that
should be always true. Here, if I'm not mistaken you use it to verify user
input. This seems a bit odd for me.

Review Comment:
What I'm not sure about is if we release 1.1.0 now with HMS_TABLE_OWNER =
"hms_table_owner" but then we change this property to
"hive.metastore.table.owner" then when this patch gets released (most probably
in 1.2.0) wouldn't it be a breaking change?
@danielcweeks could you please share your view on this?

Review Comment:
This tests that what happens when there is no specific owner/ownertype set
for the namespace but then we try to remove them, right?
What would also be beneficial in my opinion is to create the namespace with
some owner and then run a noop remove and check if the owner is still the same
what we provided during creation.

Review Comment:
I think you got me wrong. I just wanted to say that when you call
catalog.createNamespace() at L619 then you immediately call
catalog.removeNamespace(). To be on the safe side I'd add an extra check
between these two steps that right after creating the namespace the owner and
owner type are as expected.

Review Comment:
No, what I meant is to instead of this:
`String expectedOwner = "apache";
PrincipalType expectedOwnerType = PrincipalType.USER;
createNamespaceAndVerifyOwnership("userOwnership", prop, expectedOwner,
expectedOwnerType);`
we could have this:
`createNamespaceAndVerifyOwnership(
"userOwnership",
prop,
"apache",
PrincipalType.USER);`
Might be personal preference. Let me know if you feel that this wouldn't
improve readability.
