which exact version of OpenJDK are you using? Is it possible you don't have
JCE on those nodes? (I believe more recent versions of Java 8 has this
baked in so that might not be it)

I recommend taking a look at TLP-Stress as it's a bit easier to use and

Hi Kunal,
Did you edit the cassandra.yaml file in each data center to remove the seed
nodes? On which ever data center is starting from scratch (I think it's B
in your case), you may want to also change the cluster name.
