> Hcat makes multiple calls to hivemetastore client and every time the
> connection is setup and destroyed which is costly. It would be nice to have a
> centralized cache, that has a connection per unique identifier (ugi,hcat
> server uri and anything else mandatory). Instead of creating clients all over
> the code, it can be retrieved from this cache. Connections in the cache can
> be closed using WeakReference and ReferenceQueue or based on some time
> interval.
