This was a known bug in 0.8.4 and fixed in 0.8.5. </p> <p><a href="https://issues.apache.org/jira/browse/CASSANDRA-3044" rel="nofollow">https://issues.apache.org/jira/browse/CASSANDRA-3044</a></p> <p>I would recommend upgrading to the latest version of 0.8.x if possible. </p> http://www.datastax.com/support-forums/topic/opscenter-not-determining-node-ip-address-correctly#post-854 Wed, 14 Dec 2011 21:12:18 +0000 Anonymous 854@http://www.datastax.com/support-forums/ <p>I have a 3 node Cassandra cluster (0.8.4) on 3 physical hosts, and I've installed OpsCenter on one one of the hosts and have OpsCenter agent running on all 3. In the OpsCenter GUI I see "1 of 3 nodes connected", and the Ring View shows 3 nodes with IP address "45.3.96.80" (the OpsCenter host), "/45.3.96.81", and "/45.3.96.82". Note the forward slashes in the strings, which I believe to be the source of my issues.</p> <p>opscenterd.log has the following output repeatedly:<br /> 2011-12-14 15:57:45-0500 [] WARN: HTTP request <a href="https://45.3.96.80:61621/cluster/datacenter?node_ip=%2F45.3.96.81" rel="nofollow">https://45.3.96.80:61621/cluster/datacenter?node_ip=%2F45.3.96.81</a> failed: 500 Internal Server Error<br /> 2011-12-14 15:57:45-0500 [] ERROR: Error collecting datacenter: Failed query to <a href="https://45.3.96.80:61621/cluster/datacenter?node_ip=%2F45.3.96.81" rel="nofollow">https://45.3.96.80:61621/cluster/datacenter?node_ip=%2F45.3.96.81</a> : 500 Internal Server Error<br /> 2011-12-14 15:57:45-0500 [] WARN: HTTP request <a href="https://45.3.96.80:61621/cluster/datacenter?node_ip=%2F45.3.96.82" rel="nofollow">https://45.3.96.80:61621/cluster/datacenter?node_ip=%2F45.3.96.82</a> failed: 500 Internal Server Error<br /> 2011-12-14 15:57:45-0500 [] ERROR: Error collecting datacenter: Failed query to <a href="https://45.3.96.80:61621/cluster/datacenter?node_ip=%2F45.3.96.82" rel="nofollow">https://45.3.96.80:61621/cluster/datacenter?node_ip=%2F45.3.96.82</a> : 500 Internal Server Error<br /> 2011-12-14 15:58:15-0500 [] ERROR: Corrupt endpoint range data for node /45.3.96.82 on keyspace ADL_TST: [TokenRange(end_token='56713727820156410577229101238628035242', start_token<br /> ='0', endpoints=['/45.3.96.82', '/45.3.96.81', '45.3.96.80']), TokenRange(end_token='113427455640312821154458202477256070484', start_token='56713727820156410577229101238628035242',<br /> endpoints=['/45.3.96.82', '45.3.96.80', '/45.3.96.81']), TokenRange(end_token='0', start_token='113427455640312821154458202477256070484', endpoints=['/45.3.96.82', '45.3.96.80', '<br /> /45.3.96.81'])]</p> <p>I've searched around but can't seem to find anyone else with this issue in the forum. I verified that the schemas agree across nodes and I set my rpc_address to the actual public facing IP address in cassandra.yaml on each node instead of 0.0.0.0.</p> <p>Can anyone shed some light on how OpsCenter determines the IP addresses of the nodes and why it might think that my nodes' IP addresses have a slash character in them? </p>
