------------------------------------------------
Thanks for the patch [~ajayjadhav].
Can you tell us more on why you want an explicit refresh of hfiles? Ideally if
you have replication enabled it is through WAL the replication happens and if
you do not have WAL and you only have bulk loaded files we have bulk loaded
replication available.
So wit this patch - how frequently you will be invoking the new shell API?

> In the case where multiple HBase clusters are sharing a common rootDir, even
> after flushing the data from
> one cluster doesn't mean that other clusters (replicas) will automatically
> pick the new HFile. Through this patch,
> we are exposing the refresh HFiles API which when issued from a replica will
> update the in-memory file handle list
> with the newly added file.
> This allows replicas to be consistent with the data written through the
> primary cluster.
