lamber-ken edited a comment on issue #8254: [FLINK-12219][runtime] Yarn application can't stop when flink job failed in per-job yarn cluste mode URL: https://github.com/apache/flink/pull/8254#issuecomment-486714974 hi, @tillrohrmann **First**, the original exception is NPE which as [FLINK-12247](https://github.com/apache/flink/pull/8250) described. When the number of retries more than `MAX_ATTEMPTS_HISTORY_SIZE`, it'll throw NPE. The original NPE stacktrace as bellow. ``` java.lang.NullPointerException at org.apache.flink.runtime.rest.handler.util.MutableIOMetrics.addIOMetrics(MutableIOMetrics.java:88) at org.apache.flink.runtime.rest.handler.job.SubtaskExecutionAttemptDetailsHandler.createDetailsInfo(SubtaskExecutionAttemptDetailsHandler.java:140) at org.apache.flink.runtime.rest.handler.job.SubtaskExecutionAttemptDetailsHandler.archiveJsonWithPath(SubtaskExecutionAttemptDetailsHandler.java:120) at org.apache.flink.runtime.webmonitor.WebMonitorEndpoint.archiveJsonWithPath(WebMonitorEndpoint.java:780) at org.apache.flink.runtime.dispatcher.JsonResponseHistoryServerArchivist.archiveExecutionGraph(JsonResponseHistoryServerArchivist.java:57) at org.apache.flink.runtime.dispatcher.Dispatcher.archiveExecutionGraph(Dispatcher.java:758) at org.apache.flink.runtime.dispatcher.Dispatcher.jobReachedGloballyTerminalState(Dispatcher.java:730) at org.apache.flink.runtime.dispatcher.MiniDispatcher.jobReachedGloballyTerminalState(MiniDispatcher.java:138) at org.apache.flink.runtime.dispatcher.Dispatcher.lambda$startJobManagerRunner$6(Dispatcher.java:341) at java.util.concurrent.CompletableFuture.uniWhenComplete(CompletableFuture.java:760) at java.util.concurrent.CompletableFuture$UniWhenComplete.tryFire(CompletableFuture.java:736) at java.util.concurrent.CompletableFuture$Completion.run(CompletableFuture.java:442) at org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleRunAsync(AkkaRpcActor.java:332) at org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleRpcMessage(AkkaRpcActor.java:158) at org.apache.flink.runtime.rpc.akka.FencedAkkaRpcActor.handleRpcMessage(FencedAkkaRpcActor.java:70) at org.apache.flink.runtime.rpc.akka.AkkaRpcActor.onReceive(AkkaRpcActor.java:142) at org.apache.flink.runtime.rpc.akka.FencedAkkaRpcActor.onReceive(FencedAkkaRpcActor.java:40) at akka.actor.UntypedActor$$anonfun$receive$1.applyOrElse(UntypedActor.scala:165) at akka.actor.Actor$class.aroundReceive(Actor.scala:502) at akka.actor.UntypedActor.aroundReceive(UntypedActor.scala:95) at akka.actor.ActorCell.receiveMessage(ActorCell.scala:526) at akka.actor.ActorCell.invoke(ActorCell.scala:495) at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:257) at akka.dispatch.Mailbox.run(Mailbox.scala:224) at akka.dispatch.Mailbox.exec(Mailbox.scala:234) at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) at scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) at scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) at scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) ``` **Second**, the [FsJobArchivist#archiveJob](https://github.com/apache/flink/blob/6cbc9bf2cd6142c34074deaec56bb339d30b3b93/flink-runtime/src/main/java/org/apache/flink/runtime/history/FsJobArchivist.java#L71) method not only throw `IOException` but also throw `Exception`. Include at least the above exception currently. So I used `ExceptionHistoryServerArchivist` to simulate other unknown exceptions which may be happen.
