------------------------------------------------
So a general question,
I know that you need a refresh HFile in the replica. So once it refreshes it
adds to the files to the inmemory structures. But how do you manage the
archival of the files? Do you run some cleaner for that?
> Added support for clearing BlockCache

> URL: https://issues.apache.org/jira/browse/HBASE-18624
> Project: HBase
> Issue Type: Sub-task
> Affects Versions: 2.0.0, 1.3.0
> Reporter: Ajay Jadhav
> Assignee: Ajay Jadhav
> Priority: Minor
> Fix For: 1.4.0
>
>
> 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.
