Re: Cassandra install on JRE vs JDK
The ”natural” dependency of Cassandra is the JRE (not the JDK) - e.g. in the Debian package. You should be safe using JRE instead of JDK. If you’re asking whether to use a non-Oracle JVM - the answer would be: use the Oracle JVM. OpenJDK might work, but I’d not recommend it.

Re: Cassandra install on JRE vs JDK
Yes you can use Oracle JDK if your prefer, I've been using the JDK with Cassandra in production for years without issue.

Re: Cassandra install on JRE vs JDK

Re: Cassandra install on JRE vs JDK
Thanks Robert for quick response. I use Oracle JDK and not OpenJDK.
