Íñigo Goiri commented on HDFS-14284:
------------------------------------
Let's make routerId a field and add a method {{getRouterId()}} to
RouterIOException.
In addition, the message needs some spaces.
We would need to have a unit test here too.
It would be nice to be able to get the router Id automatically; is there any
static method we can get?
As follow ups, we should move other exception to use this.
[~ayushtkn] do you mind chiming in?

> The typical setup is to use multiple Routers through
> ConfiguredFailoverProxyProvider.
> In a regular HA Namenode setup, it is easy to know which NN was used.
> However, in RBF, any Router can be the one reporting the exception and it is
> hard to know which was the one.
> We should have a way to identify which Router/Namenode was the one triggering
> the exception.
> This would also apply with Observer Namenodes.
