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.
Check out the Academy FAQ pages for answers to your questions:
I was working through the DS201 "Application Connectivity" course and "Drivers" exercise and I had trouble creating a Cassandra session based on the cluster information provided:
I also verified the version of Cassandra-Driver installed as well:
Any help would be appreciated - thanks in advance.
The NoHostAvailable exception indicates that the driver was not able to connect to any nodes.
You will need to verify that Cassandra is running on the local node(localhost aka 127.0.0.1) and is listening for client connections on port 9042. If it isn't, you will need to start it as instructed in the previous step. Cheers!
After reinstalling everything, I was able to successfully create a cluster and start a session. Turns out, my 'node' folder somehow was removed at some point, so all the config information was gone as well.
I'm glad you worked it out.
It might seem frustrating at first but it's a good learning opportunity when this sort of things happen. Cheers!
