I know the message says cassandra is not available but i try making ping to the cassandra server and it work and accesing the port configured in cmb using telnet and it was open. Is this a compatibility problem? Did anyone has run on this issue before? I hope you can help me Have a good day

We have successfully tested CMB with the community version of Cassandra up to version 2.1.7. I know CMB used to work in the past with earlier versions of Datastax Enterprise but we haven't tried recently. The error message you see does sound like a configuration issue rather than a fundamental issue with the Datastax edition. Have you used earlier versions of CMB with Datastax Enterprise?

[yeiniel]

No we have not use previous versions of CMB with DSE. In the past we have always used CMB with the Datastax Comunity Edition.

The CMB contains an example schema for cassandra 12. Is there an updated schema for Cassandra 21 or Cassandra 22? Or can the 1.2 schema work effectively?

Thanks Chris

We tested the latest version of the schema (1.2) with Cassandra version 2.0.X and I would expect it to work with Cassandra 2.1/2.2 as well.

I've encountered some very similar issues to this. In the newer versions of Cassandra it appears that thrift is disabled by default, so the cmb cannot connect to it. The solution to this is to run nodetool enablethrift while Cassandra is running. This solved my connection issues. Hope this helps anyone running into similar issues!
