Hi all, We have the case of a cassandra cluster with nodes version 2.0.10, all in a single EC2 region. We want to perform a rolling upgrade to version 2.1.2 but the new node has the following exceptions:
java.lang.RuntimeException: Unable to gossip with any seeds at org.apache.cassandra.gms.Gossiper.doShadowRound(Gossiper.java:1222) ~[apache-cassandra-2.1.2.jar:2.1.2] Any ideas? The listen, rpc and seed addresses are the right ones. Thank you.
