机器参数：三台 32C64G centos 7.8，cdh集群在这上面先部署 flink版本：1.11.2，在三台集群上搭建的集群
hadoop集群是用cdh搭建的 启动命令：flink run -m yarn-cluster -ynm traffic -s 2 -p 2 -ytm 1024 -py traffic.py 程序使用pyflink开发的，从kafka读取数据，然后用滚动窗口聚合每分钟的数据在写入kafka 这个程序在local模式下是正常运行的，但是用per-job模式提交总是失败 测试官方例子 flink run -m yarn-cluster examples/batch/WordCount.jar 是可以输出结果的，所以想请教一下这个是yarn的问题还是程序的问题啊？ 下面是主要报错信息 Caused by: java.util.concurrent.CompletionException: org.apache.flink.runtime.client.JobExecutionException: Could not instantiate JobManager. at org.apache.flink.runtime.dispatcher.Dispatcher.lambda$createJobManagerRunner$6(Dispatcher.java:398) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at java.util.concurrent.CompletableFuture$AsyncSupply.run(CompletableFuture.java:1590) ~[?:1.8.0_202] at akka.dispatch.TaskInvocation.run(AbstractDispatcher.scala:40) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(ForkJoinExecutorConfigurator.scala:44) ~[flink-dist_2.12-1.11.2.jar:1.11.2] ... 4 more Caused by: org.apache.flink.runtime.client.JobExecutionException: Could not instantiate JobManager. at org.apache.flink.runtime.dispatcher.Dispatcher.lambda$createJobManagerRunner$6(Dispatcher.java:398) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at java.util.concurrent.CompletableFuture$AsyncSupply.run(CompletableFuture.java:1590) ~[?:1.8.0_202] at akka.dispatch.TaskInvocation.run(AbstractDispatcher.scala:40) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(ForkJoinExecutorConfigurator.scala:44) ~[flink-dist_2.12-1.11.2.jar:1.11.2] ... 4 more Caused by: java.io.FileNotFoundException: Cannot find checkpoint or savepoint file/directory '2' on file system 'file'. at org.apache.flink.runtime.state.filesystem.AbstractFsCheckpointStorage.resolveCheckpointPointer(AbstractFsCheckpointStorage.java:243) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.state.filesystem.AbstractFsCheckpointStorage.resolveCheckpoint(AbstractFsCheckpointStorage.java:110) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.checkpoint.CheckpointCoordinator.restoreSavepoint(CheckpointCoordinator.java:1394) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.scheduler.SchedulerBase.tryRestoreExecutionGraphFromSavepoint(SchedulerBase.java:300) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.scheduler.SchedulerBase.createAndRestoreExecutionGraph(SchedulerBase.java:253) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.scheduler.SchedulerBase.<init>(SchedulerBase.java:229) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.scheduler.DefaultScheduler.<init>(DefaultScheduler.java:119) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.scheduler.DefaultSchedulerFactory.createInstance(DefaultSchedulerFactory.java:103) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.jobmaster.JobMaster.createScheduler(JobMaster.java:284) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.jobmaster.JobMaster.<init>(JobMaster.java:272) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.jobmaster.factories.DefaultJobMasterServiceFactory.createJobMasterService(DefaultJobMasterServiceFactory.java:98) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.jobmaster.factories.DefaultJobMasterServiceFactory.createJobMasterService(DefaultJobMasterServiceFactory.java:40) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.jobmaster.JobManagerRunnerImpl.<init>(JobManagerRunnerImpl.java:140) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.dispatcher.DefaultJobManagerRunnerFactory.createJobManagerRunner(DefaultJobManagerRunnerFactory.java:84) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at org.apache.flink.runtime.dispatcher.Dispatcher.lambda$createJobManagerRunner$6(Dispatcher.java:388) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at java.util.concurrent.CompletableFuture$AsyncSupply.run(CompletableFuture.java:1590) ~[?:1.8.0_202] at akka.dispatch.TaskInvocation.run(AbstractDispatcher.scala:40) ~[flink-dist_2.12-1.11.2.jar:1.11.2] at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(ForkJoinExecutorConfigurator.scala:44) ~[flink-dist_2.12-1.11.2.jar:1.11.2] ... 4 more 2020-12-23 20:12:46,459 INFO org.apache.flink.runtime.blob.BlobServer [] - Stopped BLOB server at 0.0.0.0:16109 全部日志可以打开下面的链接：https://note.youdao.com/ynoteshare1/index.html?id=25f1af945e277057c2251e8f60d90f8a&type=note 加载可能慢一些，请稍等一会就出来了~ Best， MagicHuang
