Re: Begginer with cassandra Apache - Gossip
Hello, thanks a lot for your help :) i try to find answers to these questions: *Second Terminal:* $nodetool join This node has already joined the ring. $nodetool status Datacenter: datacenter1 === Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- AddressLoad Tokens Owns (effective) Host ID Rack *UN 127.0.0.1 83.05 KB 256 100.0% 460ddcd9-1ee8-48b8-a618-c076056aad07 rack1* Please, i have two questions: 1) i have 10 machines in my cluster, how can i create a ring on these 10 machines, i have to launch cassandra on each machine ? 2) what command can i use to see all nodes on the ring and their status (alive or not). i have already posted this question on another thread.

Would nodetool status help ( http://www.datastax.com/documentation/cassandra/2.0/cassandra/tools/toolsStatus.html ) Not sure why you trying to dig into the code?
