This implies you need to add supported OS to Ambari by yourself.

The cause is not related to Bigtop packaging.
You should consult with Ambari ML for further information.

Do you know if RHEL 8 will be supported?

Many thanks for your hard work and support!  It is appreciated.

Subject: EXTERNAL: Re: Future RHEL and CentOS support?

We moved from CentOS 8 to Rocky Linux 8 in the past.
If Rocky Linux 9 is not viable in the future, we should move to another distro 
such as CentOS Stream 9.

Since most of the products bundled by Bigtop are implemented with Java, it is 
expected to be platform-neutral basically.
Since the packages do not provide exhaustive package dependencies, building RPM 
on any Red Hat clones is expected to work with trivial fixes.
It should not matter whether it is exact clone of RHEL or not.

While we are accepting the fix for unsupported distros, pre-built binaries (for 
users' convenience) are provided for limited distros.

Due to Redhat’s recent decision to block source from downstream distros it does 
not appear that it will be possible (legally) for any distro to remain 1:1 
compatible with RHEL.  Does the Bigtop project see a way forward for supporting 
RHEL in the future?  What are the thoughts there on Redhat’s decision?
