-----------------------------------------
[~okumin] , I wrote a sample code in the following
[link|https://github.com/ngsg/hive/tree/HIVE-27473]. While the code is
incomplete and not fully organized, I check that it is compilable and passes
some of the tests. It would be appreciated if you could take a look it and
share your thoughts. Thank you.

> Project: Hive
> Issue Type: Improvement
> Components: Hive
> Affects Versions: 4.0.0-alpha-2
> Reporter: Shohei Okumiya
> Assignee: Shohei Okumiya
> Priority: Major
>
> 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.
