Now you can see the test run here: https://github.com/tuhaihe/cloudberry-pxf/actions/runs/29565211155.

Will bring the Rocky Linux 10 / Ubuntu 24.04 support later - it will be used for PXF + Cloudberry 2.2.

LGTM, checked workflow output, also compared jdk version - https://github.com/apache/cloudberry/blob/main/devops/deploy/docker/build/rocky9/Dockerfile#L117 - build container has the same version as we using in pxf smoke tests

Should we build RockyLinux & Ubuntu 22.04 with Cloudbery 2.0 (not 2.1)? Users wanted to run PXF with older cloudberry versions (#115)

UPD: it is just github-action parameters. So, no action required now.

Maybe we need to add a upgrade/downgrade test fox PXF?
