> The dfs.namenode.secondary.http-address needs to be suffixed with a
> particular nameservice. It would be useful to be able to be able to configure
> a single 2NN to checkpoint all the nameservices for a NN rather than having
> to run a separate 2NN per nameservice. It could potentially checkpoint all
> namenode IDs for a nameservice as well but given that the standby is capable
> of checkpointing and is required I think we can ignore this case.
