> RBF: The newest STANDBY and UNAVAILABLE nn should be the lowest priority.

>
> At present, when the status of all namenodes in an ns in the router is the
> same, the namenode which is the newest reported will be placed at the top of
> the cache. when the client accesses the ns through the router, it will first
> access the namenode.
> If multiple namenodes in this route are in an active state, or if there are
> namenodes with multiple observer states, the existing logic is not a problem,
> because the newest reported active or observer state namenode have a higher
> probability of being true active or observer compared to the namenode that
> reported active or observer state a long time ago.
> Similarly, the newest reported namenode with a status of standby or
> unavailable has a higher probability of being a standby or unavailable
> namenode compared to the namenode reported with a status of standby or
> unavailable a long time ago. Therefore, the newest nn reported as standby or
> unavailable status should have a lower priority for access, the oldest nn
> reported as standby or unavailable status should have a higher priority for
> access.
