Configuring JAVA_HOME for DataStax Agents
DataStax Agents do not find the environment variables of the currently logged in user by default.
If Java is not in the machine’s PATH, the Agent log shows an error on startup:
nohup: cannot run command 'java': No such file or directoryProcedure
On the 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.
For example:
JAVA_HOME = /usr/lib/jvm/java-8-oracle
