I have two versions of java (java 7 and java 8) on my machine.
JAVA_HOME set to java 7. But I want to start my cassandra with Java 8.
Is it possible to do that without changing of the JAVA_HOME value?
Change the environment variable JAVA_HOME and set it to java8 path
This change will only be impacting current running shell.
export JAVA_HOME = path_of_your_java_8
Start Cassandra in this shell
All other shell will use old java 7
