Shubham Dewan commented on HDFS-14156:
--------------------------------------
[~ayushtkn] tried as discussed , TestRouterRPC uses MiniRouterDFSCluster which
uses mockResolver instead of ActiveNamenodeResolver, thus disabling the
nameService doesn't have any affect on mockResolver(done at the time of
starting the cluster). So according to me we need to go with separate class .
