> Presently Balancer uses real URI for creating the failover proxy.
> Since the failover proxy checks for uri consistency, we should pass logical uri for creating failover proxy instead of instead of real URI. Presently will work only with default port.
> java.io.IOException: Port 49832 specified in URI hdfs://127.0.0.1:49832 but host '127.0.0.1' is a logical (HA) namenode and does not use port information.
