Start hadoop node first. </p> <p>To isolate the issue, you can roll back the changes only for node 2 and restart all the nodes to check whether it's the configuration issue at node 2? </p> http://www.datastax.com/support-forums/topic/nodetool-ring-different-on-each-server-after-changing-seeds#post-8940 Wed, 06 Feb 2013 14:10:50 +0000 schalla 8940@http://www.datastax.com/support-forums/ <p>Yes the NIC is perfectly connected and I can SSH over it. There is no typo in the seed or listen_address. I confirm. </p> http://www.datastax.com/support-forums/topic/nodetool-ring-different-on-each-server-after-changing-seeds#post-8934 Wed, 06 Feb 2013 04:57:02 +0000 Sven 8934@http://www.datastax.com/support-forums/ <p>Are you sure the NIC you are using can be used to see the other machines? One reason for this kind of issue could be that either that nic is not hooked up, or there is a firewall on. Did you check the ip address, could there be a type in the listen_address or seeds list? </p> http://www.datastax.com/support-forums/topic/nodetool-ring-different-on-each-server-after-changing-seeds#post-8933 Wed, 06 Feb 2013 04:36:28 +0000 schalla 8933@http://www.datastax.com/support-forums/ <p>I have segregated gossip and thrift traffic on its own NIC's. I did change seeds and listen_address on a three node cluster. I did this while all the nodes were down. After starting with the new configuration, one of the node is not showing up in the ring as active. Below is the nodetool ring on each host. Nodes 1 and 3 are showing up correctly. Node 2 is dead from the cluster perspective. But the gossipinfo on Node 2 shows it is gossiping with other two nodes. Not sure where to start. Any ideas?<br /> We are using DSE-2.2</p> <p>Node 1<br /> Address DC Rack Status State Load Owns Token<br /> 113427455640312821154458202477256070485<br /> 192.168.2.101 Cassandra rack1 Up Normal 494.43 MB 33.33% 0<br /> 192.168.2.102 Analytics rack1 Down Normal 479.03 MB 33.33% 56713727820156410577229101238628035242<br /> 192.168.2.103 Solr rack1 Up Normal 491.57 MB 33.33% 113427455640312821154458202477256070485 </p> <p>Node 2<br /> Address DC Rack Status State Load Owns Token<br /> 113427455640312821154458202477256070485<br /> 192.168.2.101 Analytics rack1 Down Normal ? 33.33% 0<br /> 192.168.2.102 Analytics rack1 Up Normal 485.43 MB 33.33% 56713727820156410577229101238628035242<br /> 192.168.2.103 Analytics rack1 Down Normal ? 33.33% 113427455640312821154458202477256070485 </p> <p>Node 3<br /> Address DC Rack Status State Load Owns Token<br /> 113427455640312821154458202477256070485<br /> 192.168.2.101 Cassandra rack1 Up Normal 494.43 MB 33.33% 0<br /> 192.168.2.102 Analytics rack1 Down Normal 479.03 MB 33.33% 56713727820156410577229101238628035242<br /> 192.168.2.103 Solr rack1 Up Normal 491.57 MB 33.33% 113427455640312821154458202477256070485 </p>
