> Standby Namenode has the option to do in-progress edit log tailing to improve the data freshness. In-progress tailing is already implemented, but it's not enabled as default configuration. And there's no related configuration key to turn it on.
> Adding a related configuration key to let Standby Namenode is reasonable and would be a basis for further improvement on Standby Namenode.
