Exception while trying to run multiple services connecting to same Cassandra

I am trying to run multiple services of same type connecting to a Cassandra cluster. Looks like we are hitting a race condition when running the scripts. The server fails to come up with the following exception. Please let me know if any one has faced the same issue.

The version of the software being used is 2.2.0

That is actually my plan but like everybody else I am currently working remotely and have two kids to manage as well. I will try to find some time to do this but I can currently not give you an ETA.

Hi @ysheela,

I will look into this in the next couple of days and get back to you. Maybe I can provide you with a version where the consistency level for the lead can be configured, so you can try again. As this is a race condition, I do not assume you have a reproduce-able test case?
