> 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.
