I have a RHEL 7.0 server running Cassandra 2.2.3 which I tried to upgrade to 3.0. When I run yum update it showed me there is a new version of Cassandra for update, and upgraded the server to 2.2.4-1, but not 3.0.
Now if I search yum for dsc30 I can find it, and presumably I can install it too, but why the automated upgrade doesn't happen from 2.2 to 3.0?
I've got a lot of data on my server and don't want to experiment on it. I had another test server which was running Ubuntu 14.04 and that one upgraded from 2.2 to 3.0 just fine, but on RHEL my server can't find upgrade to 3.0
Thanks
It's a different application and you can have 2.* and 3.* in parallel. Use
yum install dsc30
to install version 3.
If you want to upgrade your current installation then follow the steps described here
