> fix thread leaked when StreamTask switched from DEPLOYING to CANCELING
> ----------------------------------------------------------------------
>
> Key: FLINK-11250
> URL: https://issues.apache.org/jira/browse/FLINK-11250
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.5.6, 1.6.3, 1.7.1
> Reporter: lamber-ken
> Assignee: Anton Kalashnikov
> Priority: Minor
> Labels: auto-deprioritized-major, auto-unassigned,
> pull-request-available
> Fix For: 1.7.3
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> begin flink-1.5.x version, streamRecordWriters was created in StreamTask's
> constructor, which start OutputFlusher daemon thread. so when task switched
> from DEPLOYING to CANCELING state, the daemon thread will be leaked.
>
> *reproducible example*
> {code:java}
> public static void main(String[] args) throws Exception {
> StreamExecutionEnvironment env =
> StreamExecutionEnvironment.getExecutionEnvironment();
> env.enableCheckpointing(5000);
> env
> .addSource(new SourceFunction<String>() {
> @Override
> public void run(SourceContext<String> ctx) throws Exception {
> for (int i = 0; i < 100000000; i++) {
> Thread.sleep(100);
> ctx.collect("data " + i);
> }
> }
> @Override
> public void cancel() {
> }
> })
> .addSink(new RichSinkFunction<String>() {
> @Override
> public void open(Configuration parameters) throws Exception {
> System.out.println(1 / 0);
> }
> @Override
> public void invoke(String value, Context context) throws
> Exception {
> }
> }).setParallelism(2);
> env.execute();
> }{code}
