------------------------------------
Thanks [~surendrasingh] for opening this; we should make this part of
HDFS-13891.
Regarding the JIRA itself, I was trying to compare to the NN but it doesn't
look like the NN has an admin protocol (I thought it did).
In any case, we can just make this be like the regular RPC client and use one
of the default failover approaches.

> InetSocketAddress routerSocket = NetUtils.createSocketAddr(address);
> client = new RouterClient(routerSocket, getConf());
