CR Hota commented on HDFS-14508:
--------------------------------
[~elgoiri] Thanks for the comments.
Another way this could be thought about is to define a common interface (that
will have methods definitely for router and namenodes ex security, status,
version etc) and let NamenodeMetrics and RouterBeanmetrics extend that
interface. In future new common additions can continue to be added in commons
bean and anything specific to either namenode or router. Federation metrics
should continue to strictly have metrics only around federation.
