Coordinator stuck to replica node causing read time out

[Ranju Jain via user <us...@cassandra.apache.org>]

Hi Everyone,

Nodetool status gives Cassandra node status as [ UP ] if this machine has private interface down but public interface up.  Because this public interface is
Up, it is resulting in Cassandra node status as UP.
Due to this UP Status when coordinator is sending a read request towards this Node, it ultimately leads to read-time out.

What are the possibilities that coordinator do not send this request to this node which cannot communicate as private interface is down.

Regards
Ranju
