> When an HConnection is abort()'ed (i.e. if numerous services are lost) the
> connection becomes unusable. HConnectionManager cache of HConnections
> currently does not have any logic around removing aborted connections
> automatically. Currently it is up to the consumer to do so using
> HConnectionManager.deleteStaleConnection(HConnection).
