Description

I'd like to ensure that Zookeeper pods take priority over Solr pods, so that the ZK configuration is more likely to be available for Solr. I haven't seen a lot of how well newer versions of Solr behave when ZK is not available, but have seen problems with older versions.

Is it possible to specify priorityClassName for Zookeeper? Am I thinking about this the right way?

Research direction

The issue does not name files, tests, or entry points. Start by locating how the operator configures Zookeeper pods and Kubernetes scheduling settings; done means providing a way for Zookeeper pods to receive a priorityClassName so they take priority over Solr pods.
