> 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.
