> FLINK-25806 removed not all the legacy classes of Flink 1.15- per-component leader election. {{ZooKeeperLeaderElectionDriver}} and {{KubernetesLeaderElectionDriver}} should be removed. Tests currently implemented in {{{}ZooKeeperLeaderElectionTest{}}}, {{KubernetesLeaderElectionTest}} and {{KubernetesLeaderElectionAndRetrievalITCase}} should be removed or migrated to use {{{}MultipleComponentLeaderElection*{}}}-related classes.
