I Have modified the TestProfile.yaml as per the exercise DS210 : Configure and run cassandrastress exercise. Please find the below Testprofile.yaml file on ds210-node2 as below for your reference:
ubuntu@ds210-node2:/etc/dse/cassandra$ cat /home/ubuntu/labwork/TestProfile.yaml
#

)
#

But when Iam trying to execute the Cassandra stress from Node2(ds210-node2) using below command it is not running, output of the command as below:
