Error in NodeAutoDiscoverService for trying to connect to different ethernet address

[varun tahin]

Dear Members,

Does Cassandra support the feature to give different ethernet addresses of same server in listen address and rpc address , so as to distribute communication load(listen) and data load(RPC)?

The configuration kept in YAML file is as follows:

Same addresses for listen address and seeds

Rpc address and host address on client side  is kept same.

The cluster is running fine on Cassandra start, but is giving exception on client connection.
