All, I have a 4 node Cassandra system running on 4 Ubuntu boxes. After updating to Cassandra 2.2.0 and keeping the same cassandra.yaml file, the nodes cannot see each other.
When I do a nodetool status it only reports as being up the machine where I had issue the command. In other words, all the machines cannot communicate to each other any longer. Nodetool status behave the same on each machine. I am trying to debug that, hopefully only something on the configuration that has changed. Any ideas? Thanks. C.
