Thank you for trying out version 3.0. Currently, 3.0 has not been released yet. Upon its release, RPM packages for Rock8 and Rocky9, as well as installation packages for all related big data components, will be made available. These packages are not entirely the same as those in Bigtop—some have been patched. This will be detailed in the documentation on the new official website when the time comes.
We do not recommend upgrading from version 2.8, as there are significant code differences between 2.8 and 3.0, which will likely cause issues. The community will treat 3.0 as a long-term maintenance version moving forward. It is advisable to wait for the official release and then download all the installation packages for use together. > On Mar 25, 2025, at 03:11, Brenden Cobb <bc...@blackduck.com.INVALID> wrote: > > Hi - Anticipating the 3.0 release, I tried to upgrade an Ambari 2.8 test > cluster (docker environment, Bigtop 3.2.0, Centos 7.9) to Ambari 3.0 > (snapshot from trunk) and ran into some issues. > > When running ambari-server upgrade, some stuff from > /var/lib/ambari-server/ambari-env.sh gets reverted(?) to the older version.
