Of course. This is just the first draft.

I'd like to. That means we can collapse both call put() and delete() too. If
so, what's a good name?

Good catch. Will add it.

Will remove it.

split point is an optional row. I think we do need regioninfo.

Will move them somewhere else.

Right. Will remove it.

I can collapse it with closeRegion by making both regionInfo and
encodedRegionName optional.

For management and replication related things, should I move them to a separate
interface, called HRegionMasterInterface, HRegionManagementInterface,
HManagementInterface, or something else?
We already have a HMasterRegionInterface.
