Duo Zhang commented on HBASE-21782:
-----------------------------------
[~ndimiduk] Usually we should keep the deprecated classes for a whole major
release, as what we describe in the ref guide.
But here I define the IA.Public annotation on LoadIncrementalHFiles as a
mistake, especially that it exposes several IA.Private classes, so I used a
more aggressive policy to drop the class.
IIRC I've gotten consensus from the community. We should add a special note on
this in our ref guide too.

> It is an implementation class, so some of the methods which are only supposed
> to be used by replication sink are also public to users. And it exposes
> methods which take Table and Connection as parameter and inside the
> implementation we assume that they are HTable and ConnectionImplementation,
> which will be a pain when we want to replace the sync client implementation
> with async client.
> Here I think we should make the implementation class as
> IA.LimitPrivate(TOOL), and introduce an interface for bulking hfiles
> programmatically.
