After upgrade of cassandra from 0.8.2 to 0.8.4, got this error I have restarted cassandra, removed data, etc. nothing helps I have 6 identical machines in the cloud, before it was working fine. If I make netstat then it shows port 9160 listening nodetool ... ring - responces with 6 machines UP.
what could be the problem? : (

I don't know whether you have solved the problem. I met with the same problem as yours (Same configuration as yours too) and trrie to solve it. Problem location:
public List call() throws Exception { ... List tokens = getSubSplits(keyspace, cfName, range, conf); ...
In the method getSubSplits when calling method
createConnection(host, ConfigHelper.getRpcPort(conf), true)
, the format of host is not right. It is hostname/10.197.34.111 sometimes (ip_address), so createConnection will fail. We need to extract the ip address and then call createConnection.
You can try to change the code and try Hadoop again.
Good luck!
