Biju Nair commented on HBASE-18624:
-----------------------------------
[~ajayjadhav] Is this is to clear cache from region servers where data has been
replicated (secondary replica) for a table with read replication enabled? If
not, you may want to make this as a separate task instead of a subtask under
this umbrella ticket which is for read replication.
> 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.
