Hi, When we look at the wiki it's said :
Cassandra requires the most stable version of Java 7 you can deploy, preferably the Oracle/Sun JVM. And in chapter 4 we see that they are using Cassandra 1.2 Connected to Test Cluster at localhost:9160. [cqlsh 2.3.0 | Cassandra 1.2.2 | CQL spec 3.0.0 | Thrift protocol 19.35.0] Use HELP for help. In DataStax documentation concernning the installation on Debian they say : Install the latest version of Oracle Java SE Runtime Environment (JRE) 6 or 7. See Installing Oracle JRE on Debian or Ubuntu Systems. The fact that public updates stopped for java 6 since February 2013 should help to choose between those 2 versioins :) FYI, we choose to use Java 7 for 2 years and are happy with that in production !
