Ok, will do so, but on my nodes there shouldnt be a firewall configured. BTW: what i recognized as well (but this is then not opscenter specific) is, that the hector client is also not connecting anymore in a client i wrote:
214 [main] INFO me.prettyprint.cassandra.connection.CassandraHostRetryService - Host detected as down was added to retry queue: xx.xx.xx.xx(xx.xx.xx.xx):9160
219 [Hector.me.prettyprint.cassandra.connection.CassandraHostRetryService-1] WARN me.prettyprint.cassandra.connection.CassandraHostRetryService - Downed xxx.xx.xx.xx(xx.xx.xx.xx):9160 host still appears to be down: Unable to open transport to 78.46.
This is weird, because this also worked before with 1.0.5. Is opscenter also using hector?
