Please help me resolve this. I want to connect to my cluster and perform basic CRUD operations through Hibernate.
Also if some one can share a WORKING example to achieve this, It would be appreciated.

Thanks!

Hi,

You are using the Cassandra driver 3.0, whereas the current Hibernate OGM release has been implemented using driver 2.x.

In order to avoid this sort of issue, import the Hibernate OGM BOM POM ("bill of materials") into the <dependencyManagement> block of your project which will declare matching versions of all Hibernate OGM components and the corresponding drivers etc. Then in your <dependencies> block, just depend on group id and artifact id, the versions will be taken from the BOM declaration.

The reference guide shows how to do it:

http://docs.jboss.org/hibernate/ogm/5.0 ... ingstarted

That said, there is a pending pull request for updating to driver 3.x (https://github.com/hibernate/hibernate-ogm/pull/714), so that problem should go away soon.

I reckon it's due to using driver 2.x with Cassandra 3.x. We have a pull request for updating to driver 3.x, so you probably need until this one is merged and an OGM release has been done with it (which should be very soon).
