Task #1492

Create another cassandra dev node just like cassandra1-d-d4s.d4science.org
100%
Description
We need to experiment on Cassandra clusters, in particular to be resilient to hardware problems.
To do so, we need at least another node with the same characteristics of cassandra1-d-d4s.d4science.org. We will need an empty Cassandra so do not clone the machine, assuming you used an Ansible Playbook for cassandra1-d... it would be needed just to reapply it for cassandra2-d-...
Please, also grant me and Costantino root access

Thanks Tom, however we think you installed the latest version released (3.0.0) which requires Java 8 and is not stable like the 2.2.3 version. It should be downgraded, the same happened with the cassandra1 node, you upgraded and now we cannot use it.

packages cassandra and cassandra-tools downgraded and holded to version 2.2.3
Data and configuration are untouched.
Please close the ticket if it is all OK.
