DataStax Academy migrated to a new learning management system (LMS) in July 2020. We are also moving to a new Cassandra Certification process so there are changes to exam bookings, voucher system and issuing of certificates.

Hi,
I tried to use EC2 to set nodes for course DS210.
To set 3 nodes, I need to have 3 instances. I use the instance IAM provided by instruction.
The issue is: all the 3 instances have the same hostname which is ds210-node1, how can I change the hostname? otherwise, I'm not able to do Cassandra stress and further excercises.
Thanks
Cassandra uses IP addresses, not hostnames, and so your question doesn't make sense to me.
You need to use the public IP addresses of your EC2 instances when connecting from apps/clients such as cassandra-stress. Cheers!
