Duo Zhang commented on HBASE-21887:
-----------------------------------
For most of these projects, I think they just use HBase as an external storage,
so maybe they even do not want to start a mini cluster, just give them a client
side mock is enough? I mean, you can initialize a mocked Connection instance,
for which the data are stored in memory, and use this to test your application.
Phoenix may need to test some behaviors such as region merge/split, region
server restart, wal splitting, etc, so maybe it is an exception.

> It exposes too many internal stuffs to end user, and it is not easy to keep
> the API stable, as it is also used by us to implementing UTs.
> For end users, we should only exposes API to start a in process mini hbase
> cluster, and then user can create Connections to communicate with the
> cluster. And could exposes several APIs to start/stop/restart master
> regionservers. I think this is enough?
