I am adding a 3rd DC to the existing cassandra cluster frp migration stuff. I have updated seed hosts in the cassandra.yaml. I restartet all nodes with the new yaml file and then i started one of the new seed node and i get following WARN Message .
WARN [MessagingService-Outgoing-/192.x.x.x-Small] 2020-06-04 09:49:16,715 OutboundTcpConnection.java:436 - Seed gossip version is -2147483648; will not connect with that version.
I did a nodetool status and the new nodes is visible with Up / Normal.
I tested the connection between the nodes that should be ok.
Any Ideas many thanks in advance
