Ted Yu commented on HBASE-18624:
--------------------------------
{code}
+ public void clearBlockCache(final TableName tableName) throws IOException {
{code}
How about changing the return type to integer which represents the number of
regions who cache is not cleared ?
This would give caller some idea how effective the call is.
> Added support for clearing BlockCache based on table name

> 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.
