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

  • You are right, I could find 3.0 on yum, but what if I just want to update my 2.0 to 3.0 and keep my database as is? That's how it works on Ubuntu/Debian. I have a Ubuntu server as my dev server, and I upgraded it to 3.0 just fine, but my deployment server is RHEL and remains 2.0, now I have to use two settings in these two servers! – m.hashemian Jan 08 '16 at 14:24
  • Added the link to the upgrade documentation. – bebbo Jan 08 '16 at 16:04
  • Thanks, I'll try the link soon. It's odd that there is a different model for different architectures. – m.hashemian Jan 09 '16 at 12:34
