Re: Flink native kubernetes 下没有足够的 slot 问题
万分抱歉！邮件客户端误触发送出去了。。。 请问为什么 slot 总数充足的情况下会出现 slot 不足的异常？如何在 native kubernetes 下正确启动一个多并行度任务？ 感谢大家抽空看我的邮件！ Best, 潘 On Apr 28 2022, at 5:28 pm, Pan Junxun wrote: > 您好， > > 我最近在尝试使用 native kubernetes 方式部署 flink 集群。我根据官方文档使用 session > 模式部署了一个集群，并在上面提交了一个并行度为 5 的测试 Job，参数设置了 > -D-Dtaskmanager.numberOfTaskSlots=3。提交后可以在前端看到创建了两个 slot 数量为 3 的 > Taskmanager，并且其中有一个 Taskmanager 显示 1 slot free。但是 Job 无法正常启动，得到了 > > has no more allocated slots for job
Re: Flink native kubernetes 下没有足够的 slot 问题
Hi, Junxun 按照你的说法前半部分是符合预期的，并行度为 5 的作业需要 2 个 slot 数量为 3 的 TaskManager。 这里没看到具体的报错日志，方便提供下完成日志吗？以及对应的 flink 版本信息。 > 2022年4月28日 下午5:28，Pan Junxun 写道： > > 您好， > > 我最近在尝试使用 native kubernetes 方式部署 flink 集群。我根据官方文档使用 session > 模式部署了一个集群，并在上面提交了一个并行度为 5 的测试 Job，参数设置了 > -D-Dtaskmanager.numberOfTaskSlots=3。提交后可以在前端看到创建了两个 slot 数量为 3 的 > Taskmanager，并且其中有一个 Taskmanager 显示 1 slot free。但是 Job 无法正常启动，得到了 > > has no more allocated slots for job

Re: Flink native kubernetes 下没有足够的 slot 问题
当 SlotManager 向 TaskExecutor 为作业申请 Slot 后，TaskExecutor 会向 JobMaster offer这些 Slots。从 TaskExecutor 接受到 SlotManager 的请求后会注册一个定时器，如果在定时器计时结束时仍然没有将 Slots offer 给 JobMaster，会触发这个问题。 Slot timeout 的时间配置项为taskmanager.slot.timeout，如果没有单独配置，则使用 akka.ask.timeout 的值（默认为 10s）。 可以尝试增加 taskmanager.slot.timeout 超时来避免这个问题，如果仍然有问题，需要进一步通过 JobManager/TaskManager 日志进行分析。 > 2022年4月28日 下午8:04，Pan Junxun 写道： > > 感谢回复！ > > 日志内容如下： > > 2022-04-28 19:58:20 > org.apache.flink.runtime.JobException: Recovery is suppressed by > NoRestartBackoffTimeStrategy > at > org.apache.flink.runtime.executiongraph.failover.flip1.ExecutionFailureHandler.handleFailure(ExecutionFailureHandler.java:138) > at > org.apache.flink.runtime.executiongraph.failover.flip1.ExecutionFailureHandler.getFailureHandlingResult(ExecutionFailureHandler.java:82) > at > org.apache.flink.runtime.scheduler.DefaultScheduler.handleTaskFailure(DefaultScheduler.java:207) > at > org.apache.flink.runtime.scheduler.DefaultScheduler.maybeHandleTaskFailure(DefaultScheduler.java:197) > at > org.apache.flink.runtime.scheduler.DefaultScheduler.updateTaskExecutionStateInternal(DefaultScheduler.java:188) > at > org.apache.flink.runtime.scheduler.SchedulerBase.updateTaskExecutionState(SchedulerBase.java:677) > at > org.apache.flink.runtime.scheduler.UpdateSchedulerNgOnInternalFailuresListener.notifyTaskFailure(UpdateSchedulerNgOnInternalFailuresListener.java:51) > at > org.apache.flink.runtime.executiongraph.DefaultExecutionGraph.notifySchedulerNgAboutInternalTaskFailure(DefaultExecutionGraph.java:1462) > at > org.apache.flink.runtime.executiongraph.Execution.processFail(Execution.java:1140) > at > org.apache.flink.runtime.executiongraph.Execution.processFail(Execution.java:1080) > at org.apache.flink.runtime.executiongraph.Execution.fail(Execution.java:783) > at > org.apache.flink.runtime.jobmaster.slotpool.SingleLogicalSlot.signalPayloadRelease(SingleLogicalSlot.java:195) > at > org.apache.flink.runtime.jobmaster.slotpool.SingleLogicalSlot.release(SingleLogicalSlot.java:182) > at > org.apache.flink.runtime.scheduler.SharedSlot.lambda$release$4(SharedSlot.java:271) > at > java.util.concurrent.CompletableFuture.uniAccept(CompletableFuture.java:670) > at > java.util.concurrent.CompletableFuture.uniAcceptStage(CompletableFuture.java:683) > at > java.util.concurrent.CompletableFuture.thenAccept(CompletableFuture.java:2010) > at org.apache.flink.runtime.scheduler.SharedSlot.release(SharedSlot.java:271) > at > org.apache.flink.runtime.jobmaster.slotpool.AllocatedSlot.releasePayload(AllocatedSlot.java:152) > at > org.apache.flink.runtime.jobmaster.slotpool.DefaultDeclarativeSlotPool.releasePayload(DefaultDeclarativeSlotPool.java:385) > at > org.apache.flink.runtime.jobmaster.slotpool.DefaultDeclarativeSlotPool.releaseSlots(DefaultDeclarativeSlotPool.java:361) > at > org.apache.flink.runtime.jobmaster.slotpool.DeclarativeSlotPoolService.internalReleaseTaskManager(DeclarativeSlotPoolService.java:249) > at > org.apache.flink.runtime.jobmaster.slotpool.DeclarativeSlotPoolService.releaseTaskManager(DeclarativeSlotPoolService.java:230) > at > org.apache.flink.runtime.jobmaster.JobMaster.disconnectTaskManager(JobMaster.java:497) > at sun.reflect.GeneratedMethodAccessor591.invoke(Unknown Source) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at > org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleRpcInvocation(AkkaRpcActor.java:305) > at > org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleRpcMessage(AkkaRpcActor.java:212) > at > org.apache.flink.runtime.rpc.akka.FencedAkkaRpcActor.handleRpcMessage(FencedAkkaRpcActor.java:77) > at > org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleMessage(AkkaRpcActor.java:158) > at akka.japi.pf.UnitCaseStatement.apply(CaseStatements.scala:26) > at akka.japi.pf.UnitCaseStatement.apply(CaseStatements.scala:21) > at scala.PartialFunction.applyOrElse(PartialFunction.scala:123) > at scala.PartialFunction.applyOrElse$(PartialFunction.scala:122) > at akka.japi.pf.UnitCaseStatement.applyOrElse(CaseStatements.scala:21) > at scala.PartialFunction$OrElse.applyOrElse(PartialFunction.scala:171) > at scala.PartialFunction$OrElse.applyOrElse(PartialFunction.scala:172) > at scala.PartialFunction$OrElse.applyOrElse(PartialFunction.scala:172) > at akka.actor.Actor.aroundReceive(Actor.scala:517) > at akka.actor.Actor.aroundReceive$(Actor.scala:515) > at akka.actor.AbstractActor.aroundReceive(AbstractActor.scala:225) > at akka.actor.ActorCell.receiveMessage(ActorCell.scala:592) > at akka.actor.ActorCell.invoke(ActorCell.scala:561) > at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:258) > at akka.dispatch.Mailbox.run(Mailbox.scala:225) > at akka.dispatch.Mailbox.exec(Mailbox.scala:235) > at akka.dispatch.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) > at > akka.dispatch.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:13

最后的解决方案是在 kubernetes-session.sh 启动参数中增加： -Dakka.ask.timeout=100s -Dweb.timeout=100 或者直接修改 configmap 中的 flink-conf.yml 经过多次测试，该问题的根源应该是 slot 太多导致初始的 1ms timeout 不够用，但 1.13 增加参数后仍会出现异常，1.14 则没有问题。 再次感谢 huweihua On Apr 29 2022, at 9:49 am, Pan Junxun wrote: > 感谢大佬指点，我换到 1.14.4 后这个问题解决了 > > On Apr 28 2022, at 9:03 pm, huweihua wrote: > > 当 SlotManager 向 TaskExecutor 为作业申请 Slot 后，TaskExecutor 会向 JobMaster offer这些 > > Slots。从 TaskExecutor 接受到 SlotManager 的请求后会注册一个定时器，如果在定时器计时结束时仍然没有将 Slots > > offer 给 JobMaster，会触发这个问题。 > > > > Slot timeout 的时间配置项为taskmanager.slot.timeout，如果没有单独配置，则使用 akka.ask.timeout > > 的值（默认为 10s）。 > > 可以尝试增加 taskmanager.slot.timeout 超时来避免这个问题，如果仍然有问题，需要进一步通过 > > JobManager/TaskManager 日志进行分析。 > > > 2022年4月28日 下午8:04，Pan Junxun 写道： > > > > > > 感谢回复！ > > > > > > 日志内容如下： > > > > > > 2022-04-28 19:58:20 > > > org.apache.flink.runtime.JobException: Recovery is suppressed by > > > NoRestartBackoffTimeStrategy > > > at > > > org.apache.flink.runtime.executiongraph.failover.flip1.ExecutionFailureHandler.handleFailure(ExecutionFailureHandler.java:138) > > > at > > > org.apache.flink.runtime.executiongraph.failover.flip1.ExecutionFailureHandler.getFailureHandlingResult(ExecutionFailureHandler.java:82) > > > at > > > org.apache.flink.runtime.scheduler.DefaultScheduler.handleTaskFailure(DefaultScheduler.java:207) > > > at > > > org.apache.flink.runtime.scheduler.DefaultScheduler.maybeHandleTaskFailure(DefaultScheduler.java:197) > > > at > > > org.apache.flink.runtime.scheduler.DefaultScheduler.updateTaskExecutionStateInternal(DefaultScheduler.java:188) > > > at > > > org.apache.flink.runtime.scheduler.SchedulerBase.updateTaskExecutionState(SchedulerBase.java:677) > > > at > > > org.apache.flink.runtime.scheduler.UpdateSchedulerNgOnInternalFailuresListener.notifyTaskFailure(UpdateSchedulerNgOnInternalFailuresListener.java:51) > > > at > > > org.apache.flink.runtime.executiongraph.DefaultExecutionGraph.notifySchedulerNgAboutInternalTaskFailure(DefaultExecutionGraph.java:1462) > > > at > > > org.apache.flink.runtime.executiongraph.Execution.processFail(Execution.java:1140) > > > at > > > org.apache.flink.runtime.executiongraph.Execution.processFail(Execution.java:1080) > > > at > > > org.apache.flink.runtime.executiongraph.Execution.fail(Execution.java:783) > > > at > > > org.apache.flink.runtime.jobmaster.slotpool.SingleLogicalSlot.signalPayloadRelease(SingleLogicalSlot.java:195) > > > at > > > org.apache.flink.runtime.jobmaster.slotpool.SingleLogicalSlot.release(SingleLogicalSlot.java:182) > > > at > > > org.apache.flink.runtime.scheduler.SharedSlot.lambda$release$4(SharedSlot.java:271) > > > at > > > java.util.concurrent.CompletableFuture.uniAccept(CompletableFuture.java:670) > > > at > > > java.util.concurrent.CompletableFuture.uniAcceptStage(CompletableFuture.java:683) > > > at > > > java.util.concurrent.CompletableFuture.thenAccept(CompletableFuture.java:2010) > > > at > > > org.apache.flink.runtime.scheduler.SharedSlot.release(SharedSlot.java:271) > > > at > > > org.apache.flink.runtime.jobmaster.slotpool.AllocatedSlot.releasePayload(AllocatedSlot.java:152) > > > at > > > org.apache.flink.runtime.jobmaster.slotpool.DefaultDeclarativeSlotPool.releasePayload(DefaultDeclarativeSlotPool.java:385) > > > at > > > org.apache.flink.runtime.jobmaster.slotpool.DefaultDeclarativeSlotPool.releaseSlots(DefaultDeclarativeSlotPool.java:361) > > > at > > > org.apache.flink.runtime.jobmaster.slotpool.DeclarativeSlotPoolService.internalReleaseTaskManager(DeclarativeSlotPoolService.java:249) > > > at > > > org.apache.flink.runtime.jobmaster.slotpool.DeclarativeSlotPoolService.releaseTaskManager(DeclarativeSlotPoolService.java:230) > > > at > > > org.apache.flink.runtime.jobmaster.JobMaster.disconnectTaskManager(JobMaster.java:497) > > > at sun.reflect.GeneratedMethodAccessor591.invoke(Unknown Source) > > > at > > > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > > > at java.lang.reflect.Method.invoke(Method.java:498) > > > at > > > org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleRpcInvocation(AkkaRpcActor.java:305) > > > at > > > org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleRpcMessage(AkkaRpcActor.java:212) > > > at > > > org.apache.flink.runtime.rpc.akka.FencedAkkaRpcActor.handleRpcMessage(FencedAkkaRpcActor.java:77) > > > at > > > org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleMessage(AkkaRpcActor.java:158) > > > at akka.japi.pf.UnitCaseStatement.apply(CaseStatements.scala:26) > > > at akka.japi.pf.UnitCaseStatement.apply(CaseStatements.scala:21) > > > at scala.PartialFunction.applyOrElse(PartialFunction.scala:123) > > > at scala.PartialFunction.applyOrElse$(PartialFunction.scala:122) > > > at akka.japi.pf.UnitCaseStatement.applyOrElse(CaseStatements.scala:21) > > > at scala.PartialFunction$OrElse.applyOrElse(PartialFunction.scala:171) > > > at scala.PartialFunction$OrElse.applyOrElse(PartialFunction.scala:172) >
