HBASE-23648: Re-use underlying connection registry in RawAsyncHBaseAdmin

[bharathv]

No need to create and close a new registry on demand. Audited other
usages of getRegistry() and the code looks fine.

[bharathv]

@saintstack / @Apache9 A small fix that fixes ad-hoc creation of registries. I audited the code and other invocations look fine.

Existing test coverage should be good enough, hence no new tests are added.

LGTM. Where does it get committed? On branch? Leaving it for a day in case @Apache9 wants to take a look.

For the future, try to minimize your changes. Most of the below is just refactoring. Takes a while to verify no accidental breakage. For the future.

Good stuff.

[bharathv]

LGTM. Where does it get committed? On branch?

Yes please, feature branch. It builds on the "ConnectionRegistry" change that exists only in the branch. I'm hoping the branch gets merged into the master soon.

Ack. I see your point. Generally I'm trying to fix all the check style issues around the places I'm touching, there are tons of violations. But I guess it is better to bulk fix them in separate changes.

[bharathv]

@saintstack is this good to go? thanks for the review.

[saintstack]

Sorry @bharathv I left it too long? There are conflicts? Mind fixing please?

[bharathv]

@saintstack No problemo! Appreciate the reviews.
