Subject Re: What is the best way to install & upgrade Cassandra on Ubuntu ?
Date Fri, 04 Oct 2013 04:13:04 GMT
Thanks for clarifications!
Btw DSC installs OpenJDK when java is not present on your system. Don't
know why it doesn't include just the preferred Oracle JRE installation &
take care of later updates to that as well, so that could be a reason to
choose DSC over official apache Debian(as that would be complete package to
run cassandra), otherwise I can't see any strong reasons to prefer it !?
