Configuring JAVA_HOME for DataStax agents
DataStax agents do not pick up the environment variables of the currently logged-in user by default.
For example, if Java is not in the machine's PATH, you may notice errors in the agent log on start-up:
nohup: cannot run command 'java': No such file or directory
Procedure
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 may need. For example:
export JAVA_HOME = /usr/bin/java
