Sorry, made a stupid mistake here... It should be added in
`HiveContext.newTemporaryConfigurations()` Unfortunately I couldn't figure out
a way to add a regression test for this change since it requires a remote Hive
metastore to test. I was verifying the result by remote debugging and checking
the internal underlying Hive metastore client instance of `executionHive`.
Somehow came to the wrong conclusion :(
