Hi,

would you give us a more context how you are running into this issue?

There could be a number of reason why you are seeing this. For example, the node could be down or not yet fully started, as nodetool won't connect until the node is fully started.

Are you experimenting with a virtual machine from one of the Academy courses?

There isn't enough information in your post but if you're having issues with the VM for the Data Modeling course (DS220) at DataStax Academy, it's a known issue which you should be able to diagnose yourself :) if you've completed the Cassandra Foundations course (DS201) and possibly the Cassandra Operations course (DS210).

Cause

DSE does not start in the VM since it's configured in cassandra.yaml to run on an IP which is not available on your PC/laptop:

listen_address: 10.0.2.15
          - seeds: "10.0.2.15"

Workaround

Reconfigure /etc/dse/cassandra/cassandra.yaml on your VM.

STEP 1 - Set the seeds list to use the loopback IP:

          - seeds: "127.0.0.1"

STEP 2 - Set the listen_address to localhost:

listen_address: localhost

STEP 3 - Save the changes to cassandra.yaml.

STEP 4 - Start DSE on the VM:

$ sudo service dse start

If your question isn't related to the DS220 VM, feel free to update your original question with the details and I'd be happy to amend my answers. Cheers!
