Till Rohrmann created FLINK-20992: ------------------------------------- Summary: Checkpoint cleanup can kill JobMaster Key: FLINK-20992 URL: https://issues.apache.org/jira/browse/FLINK-20992 Project: Flink Issue Type: Bug Components: Runtime / Checkpointing Affects Versions: 1.12.0 Reporter: Till Rohrmann Fix For: 1.13.0, 1.12.2
A user reported that cancelling a job can lead to an uncaught exception which kills the {{JobMaster}}. The problem seems to be that the {{CheckpointsCleaner}} might trigger {{CheckpointCoordinator}} actions after the job has reached a terminal state and, thus, is shut down. Apparently, we do not properly manage the lifecycles of {{CheckpointCoordinator}} and checkpoint post clean up actions. The uncaught exception is {code} java.util.concurrent.RejectedExecutionException: Task java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask@41554407 rejected from java.util.concurrent.ScheduledThreadPoolExecutor@5d0ec6f7[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 25977] at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2063 at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:830 at java.util.concurrent.ScheduledThreadPoolExecutor.delayedExecute(ScheduledThreadPoolExecutor.java:326 at java.util.concurrent.ScheduledThreadPoolExecutor.schedule(ScheduledThreadPoolExecutor.java:533 at java.util.concurrent.ScheduledThreadPoolExecutor.execute(ScheduledThreadPoolExecutor.java:622 at java.util.concurrent.Executors$DelegatedExecutorService.execute(Executors.java:668 at org.apache.flink.runtime.concurrent.ScheduledExecutorServiceAdapter.execute(ScheduledExecutorServiceAdapter.java:62 at org.apache.flink.runtime.checkpoint.CheckpointCoordinator.scheduleTriggerRequest(CheckpointCoordinator.java:1152 at org.apache.flink.runtime.checkpoint.CheckpointsCleaner.lambda$cleanCheckpoint$0(CheckpointsCleaner.java:58 at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149 at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624 at java.lang.Thread.run(Thread.java:748 undefined) {code} cc [~roman_khachatryan]. https://lists.apache.org/thread.html/r75901008d88163560aabb8ab6fc458cd9d4f19076e03ae85e00f9a3a%40%3Cuser.flink.apache.org%3E -- This message was sent by Atlassian Jira (v8.3.4#803005)
