>
> 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.
