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. > Am 18.02.2015 um 20:49 schrieb cass savy <casss...@gmail.com>: > > Can we install Oracle JDK instead of JRE in Cassandra servers?
