Gyula Fora commented on FLINK-30313: ------------------------------------ At this point operator should not contain any 1.16 dependencies on the classpath so I don’t see how this error may occur. Especially not the 1.2.0 version which was released before Flink 1.16.0 I think. could something in the user image cause this problem? > Flink Kubernetes Operator seems to rely on 1.15 k8s HA code but 1.16 config > code > -------------------------------------------------------------------------------- > > Key: FLINK-30313 > URL: https://issues.apache.org/jira/browse/FLINK-30313 > Project: Flink > Issue Type: Bug > Components: Kubernetes Operator > Affects Versions: kubernetes-operator-1.2.0 > Reporter: Matthias Pohl > Priority: Major > > Based on [this SO > post|https://stackoverflow.com/questions/74599009/flink1-16-high-availability-job-manager], > it looks like there can be a setup where we use different versions of Flink: > {code} > 2022-11-28 08:57:56.032 [main] INFO > org.apache.flink.runtime.entrypoint.ClusterEntrypoint - Shutting > KubernetesApplicationClusterEntrypoint down with application status FAILED. > Diagnostics java.lang.NoSuchFieldError: USE_OLD_HA_SERVICES > at > org.apache.flink.kubernetes.highavailability.KubernetesHaServicesFactory.createHAServices(KubernetesHaServicesFactory.java:37) > at > org.apache.flink.runtime.highavailability.HighAvailabilityServicesUtils.createCustomHAServices(HighAvailabilityServicesUtils.java:296) > at > org.apache.flink.runtime.highavailability.HighAvailabilityServicesUtils.createHighAvailabilityServices(HighAvailabilityServicesUtils.java:139) > at > org.apache.flink.runtime.entrypoint.ClusterEntrypoint.createHaServices(ClusterEntrypoint.java:439) > at > org.apache.flink.runtime.entrypoint.ClusterEntrypoint.initializeServices(ClusterEntrypoint.java:382) > at > org.apache.flink.runtime.entrypoint.ClusterEntrypoint.runCluster(ClusterEntrypoint.java:282) > at > org.apache.flink.runtime.entrypoint.ClusterEntrypoint.lambda$startCluster$1(ClusterEntrypoint.java:232) > at > org.apache.flink.runtime.security.contexts.NoOpSecurityContext.runSecured(NoOpSecurityContext.java:28) > at > org.apache.flink.runtime.entrypoint.ClusterEntrypoint.startCluster(ClusterEntrypoint.java:229) > at > org.apache.flink.runtime.entrypoint.ClusterEntrypoint.runClusterEntrypoint(ClusterEntrypoint.java:729) > at > org.apache.flink.kubernetes.entrypoint.KubernetesApplicationClusterEntrypoint.main(KubernetesApplicationClusterEntrypoint.java:86) > {code} > This field was removed in FLINK-25806 with Flink 1.16.
