Clustering : 3 Node Clustering of ODL is not working

HI,
am trying out the clustering of ODL, as mentioned in the
https://wiki.opendaylight.org/view/Running_and_testing_an_OpenDaylight_Cluster
i have an issue here.
After i configure the 2 nodes (according to the WiKi) and started the controllers with karaf command, i have the following issues:
1. When i try to access the dlux UI (of the controller IP, which we gave in akka.conf), it says Unable to login.
2. On the node controller, i have the following error message (not able to connect to the controller):
