> Currently, we implement the two classes using inheritance. It assumes we 
> always use a single implementation of IMetaStoreClient.
> Some community members have been willing to make IMetaStoreClient pluggable 
> as proposed in HIVE-12679. Considering the use case, we should provide the 
> additional traits with composition over inheritance.
