> When there is some unexpected network outage or client-side issue, the
> network connection could stay alive forever, due to the lack of keep alive.
> We have observed such dead connection in name node. Though it has no known
> performance hits, but it is a waste of resource. Adding SO_KEEPALIVE to all
> accepted sockets should not be heavy, since the keep alive TCP packets will
> only be sent once every four hours.
