> Since `HiveClient` is used to interact with the Hive metastore, it should be
> hidden in `HiveExternalCatalog`. After moving `HiveClient` into
> `HiveExternalCatalog`, `HiveSharedState` becomes a wrapper of
> `HiveExternalCatalog`. Thus, removal of `HiveSharedState` becomes
> straightforward. After removal of `HiveSharedState`, the reflection logic is
> directly applied on the choice of `ExternalCatalog` types, based on the
> configuration of `CATALOG_IMPLEMENTATION`.
> `HiveClient` is also used/invoked by the other entities besides
> HiveExternalCatalog, we defines the following two APIs:
> {noformat}
> /**
>* Return the existing [[HiveClient]] used to interact with the metastore.
>*/
> def getClient: HiveClient
> /**
>* Return a [[HiveClient]] as a new session
>*/
> def getNewClient: HiveClient
> {noformat}
