------------------------------------------------
[~ajayjadhav]
Thanks for the patch. I think even this you can go with end point type of
implementation. Adding this in Admin is too generic and may be not useful. If
this type of API is at Table / Region level it is alteast better but not at
Admin level.
I saw your other comments where you say this API is good for all use cases but
still Admin level is not the expected way I believe.

> Bulk loading the primary HBase cluster triggers a lot of compactions
> resulting in archival/ creation
> of multiple HFiles. This process will cause a lot of items to become stale in
> replica’s BlockCache.
> This patch will help users to clear the block cache for a given table by
> either using shell or API.
