Solution
The Cassandra documentation says "On the Cassandra nodes where the agents are installed, create the file /etc/default/datastax-agent and set the environment variables for JAVA_HOME and any other custom environment variables that the agent might need." https://docs.datastax.com/en/opscenter/6.1/opsc/install/opscCustomVariables_t.html
