Description

https://github.com/apache/hadoop/blob/HDFS-13891/hadoop-hdfs-project/hadoop-hdfs-rbf/src/test/java/org/apache/hadoop/hdfs/server/federation/MiniRouterDFSCluster.java#L808

the comment says one router is created per name service, while in the code one router is created per namenode in each nameservice.

There are a couple of things that might need to consider optimization:

1. make the code as the the comment
2. add some ways to specify the number of routers
