> The FenceMethod interface passes along the host:port of the NN that needs to
> be fenced. That's great for the common case. However, it's likely necessary
> to have extra configuration parameters for fencing, and these are typically
> keyed off the nameserviceId.namenodeId (if, for nothing else, consistency
> with all the other parameters that are keyed off of namespaceId.namenodeId).
> Obviously this can be backed out from the host:port, but it's inconvenient,
> and requires iterating through all the configs.
> The shell interface exhibits the same issue: host:port is great for most
> fencers, but if you need extra configs (like the host:port of the power
> supply unit), those are harder to pipe through without the namenodeId.
