> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Task
> Affects Versions: 1.11.0, 1.12.0
> Reporter: YufeiLiu
> Priority: Major
> Labels: stale-major
>
> If a operator throw a exception, it will break process loop and dispose all
> operator. But state will never switch to FAILED if block in Function.close,
> and JobMaster can't know the final state and do restart.
> Task have {{TaskCancelerWatchDog}} to kill process if cancellation timeout,
> but it doesn't work for FAILED task.TAskThread will allways hang at:
> org.apache.flink.streaming.runtime.tasks.StreamTask#cleanUpInvoke
> Test case:
> {code:java}
> Configuration configuration = new Configuration();
> configuration.set(TaskManagerOptions.TASK_CANCELLATION_TIMEOUT, 10000L);
> StreamExecutionEnvironment env =
> StreamExecutionEnvironment.createLocalEnvironment(2, configuration);
> env.addSource(...)
> .process(new ProcessFunction<String, String>() {
> @Override
> public void processElement(String value, Context ctx,
> Collector<String> out) throws Exception {
> if (getRuntimeContext().getIndexOfThisSubtask() == 0) {
> throw new RuntimeException();
> }
> }
> @Override
> public void close() throws Exception {
> if (getRuntimeContext().getIndexOfThisSubtask() == 0) {
> Thread.sleep(10000000);
> }
> }
> }).setParallelism(2)
> .print();
> {code}
> In this case, job will block at close action and never change to FAILED.
> If change thread which subtaskIndex == 1 to sleep, TM will exit after
> TASK_CANCELLATION_TIMEOUT.
