Íñigo Goiri commented on HDFS-14508:
------------------------------------
I wanted to keep {{NamenodeBeanMetrics}} to offer the same interface as the
Namenode.
We always though of the Router as a replacement for the Namenode as an endpoint
so the goal here was to allow old monitors to just change the port.
I would prefer to keep it for this reason.
That being said, it is true that some of the methods don't make much sense for
some metrics.
For methods like getSlowPeersReport and getSlowDisksReport, ideally we should
be able to aggregate those from all subclusters.
