[jira] [Created] (FLINK-26476) Introduce flink-kubernetes-shaded to avoid overlapping classes

Yang Wang created FLINK-26476:
---------------------------------

             Summary: Introduce flink-kubernetes-shaded to avoid overlapping classes
                 Key: FLINK-26476
                 URL: https://issues.apache.org/jira/browse/FLINK-26476
             Project: Flink
          Issue Type: Sub-task
          Components: Kubernetes Operator
            Reporter: Yang Wang


When we compile the flink-kubernetes-operator, we could find the following overlapping classes of fabric8 kubernetes client dependencies. I propose to add a flink-kubernetes-shaded module to fix this in current project. If we are confident enough the shading works well, I will contribute it to the upstream project Flink.
