The current build for YuniKorn uses 1.20.11. Even a small change to K8s 1.21 causes compilation issues.
Some issues can be solved by a simple one or two code line change.
There is at least one that requires a major change in the predicate code to accomodate fundamental changes made to the plugin framework.
Given that compiling against 1.24 or later prevents running on 1.23 or earlier, we should build against 1.23.x. This will allow us to maintain support for running on 1.21 and later while also supporting newer scheduler features.
