Cassandra Opscenter, connected to the cluster, But No Node information get listed

configration is pretty simple for opscenter, just change files under conf fodler, point to correct seed server, then I can query the data from Opscenter now.

How ever, the dashboard, there is no node information.

When I check the logs under opscenter , when it try to get node infrmation from the thift API, get error, that explains why, return no results.

After did a lot testing, I noticed this is because of the version mismatch, for Cassandra cluster, it runs on 1.0 version.

while the ops center version is 1.3.1, you can tell from the console on the left bottom

then I try update the Cassandra to the latest version 1.0.5, it works without any problem.
