Hi！ io.fabric8.kubernetes.client.KubernetesClientException: too old resource version 这个问题可能是由于 Pod 和 APIServer之间的网络不稳定。这个问题已经在 1.12.2 版本被修复，详见 https://issues.apache.org/jira/browse/FLINK-20417
建议使用 Flink 1.12.x 的最新版本。 blue <[email protected]> 于2021年8月26日周四 下午5:30写道： > Hi， > flink 1.12.1 on native k8s > application模式，jobManager频繁重启可能是什么原因导致的，报错日志如下： > > > "2021-08-26 12:41:12,891 DEBUG > org.apache.flink.runtime.io.network.partition.ResourceManagerPartitionTrackerImpl > [] - Processing cluster partition report from task executor > tb-bipo-upload-file-info-binlog2mongo-taskmanager-50-1: > PartitionReport{entries=[]}." > > > "2021-08-26 12:41:13,082 DEBUG > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager [] - > Connecting websocket ... > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager@7799909e" > > > "2021-08-26 12:41:13,085 DEBUG > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager [] - > WebSocket successfully opened" > > > "2021-08-26 12:41:13,093 ERROR > org.apache.flink.runtime.jobmaster.JobManagerRunnerImpl [] - Leader > Election Service encountered a fatal error." > > > "org.apache.flink.runtime.leaderelection.LeaderElectionException: Error > while watching the ConfigMap > tb-bipo-upload-file-info-binlog2mongo-ef82295e3efde28d7b424565606753e0-jobmanager-leader" > > > "at > org.apache.flink.kubernetes.highavailability.KubernetesLeaderElectionDriver$ConfigMapCallbackHandlerImpl.handleFatalError(KubernetesLeaderElectionDriver.java:251) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > org.apache.flink.kubernetes.kubeclient.resources.AbstractKubernetesWatcher.onClose(AbstractKubernetesWatcher.java:48) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > io.fabric8.kubernetes.client.utils.WatcherToggle.onClose(WatcherToggle.java:56) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager.closeEvent(WatchConnectionManager.java:367) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager.access$700(WatchConnectionManager.java:50) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager$1.onMessage(WatchConnectionManager.java:259) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > org.apache.flink.kubernetes.shaded.okhttp3.internal.ws.RealWebSocket.onReadMessage(RealWebSocket.java:323) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > org.apache.flink.kubernetes.shaded.okhttp3.internal.ws.WebSocketReader.readMessageFrame(WebSocketReader.java:219) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > org.apache.flink.kubernetes.shaded.okhttp3.internal.ws.WebSocketReader.processNextFrame(WebSocketReader.java:105) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > org.apache.flink.kubernetes.shaded.okhttp3.internal.ws.RealWebSocket.loopReader(RealWebSocket.java:274) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > org.apache.flink.kubernetes.shaded.okhttp3.internal.ws.RealWebSocket$2.onResponse(RealWebSocket.java:214) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > org.apache.flink.kubernetes.shaded.okhttp3.RealCall$AsyncCall.execute(RealCall.java:206) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > org.apache.flink.kubernetes.shaded.okhttp3.internal.NamedRunnable.run(NamedRunnable.java:32) > [flink-dist_2.12-1.12.1.jar:1.12.1]" > > > "at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) > [?:1.8.0_292]" > > > "at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) > [?:1.8.0_292]" > > > "at java.lang.Thread.run(Thread.java:748) [?:1.8.0_292]" > > > "Caused by: io.fabric8.kubernetes.client.KubernetesClientException: too > old resource version: 2137353712 (2137353732)" > > > "... 11 more" > > > "2021-08-26 12:41:13,093 DEBUG > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager [] - Force > closing the watch > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager@7799909e" > > > "2021-08-26 12:41:13,093 DEBUG > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager [] - > Ignoring duplicate firing of onClose event" > > > "2021-08-26 12:41:13,094 DEBUG > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager [] - > WebSocket close received. code: 1000, reason: " > > > "2021-08-26 12:41:13,094 DEBUG > io.fabric8.kubernetes.client.dsl.internal.WatchConnectionManager [] - > Ignoring onClose for already closed/closing websocket" > > > "2021-08-26 12:41:13,095 ERROR > org.apache.flink.runtime.entrypoint.ClusterEntrypoint [] - Fatal > error occurred in the cluster entrypoint." > > > "org.apache.flink.util.FlinkException: JobMaster for job > ef82295e3efde28d7b424565606753e0 failed."
