Cassandra should be installed in /workspace/ds201-lab06/apache-cassandra-4.1.0/.
✅ Change to the ./bin directory:
cd /workspace/ds201-lab06/apache-cassandra-4.1.0/bin
✅ Look for nodetool in the directory:
ls -l
✅ Run nodetool with the help command and take your time to learn about various available commands:
./nodetool help
Some commands display information about the entire cluster and its nodes. Others may be specific to a node you connect to.
Note: The following commands have to connect to a running Cassandra node to get information about the cluster. You may have to run them more than once if your node(s) are not yet up.
✅ Run nodetool with the describecluster command to display high-level information about the cluster:
./nodetool describecluster
✅ Run nodetool with the status command to display information about all nodes in the cluster:
./nodetool status
For each node, you should be able to see its state, IP address, load, and so forth.
✅ Run nodetool with the info command to display information about this node:
./nodetool info
Take your time to read through all the information pieces.
