Ajay Jadhav commented on HBASE-18624:
-------------------------------------
Regarding the exception: The NotServingRegionException can only happen in case
the meta table is corrupted resulting in providing an incorrect location for a
region. This may also happen due to some region operation in progress (split)
etc which meta is not aware of. In case I rethrow the exception it will stop
the processing of all the subsequent regions due to one bad entry in meta.
Also, this will be one-off case due to which I'm just logging the exception.
I'll move HBaseRpcController out of for loop. Thanks.

> 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.
