### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version 3.0.0 ### Minimal reproduce step 1. I have code as following to sync data from pulsar into hdfs ` public static void main(String[] args) throws Exception { StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment(); // env.socketTextStream("10.180.85.1", 8081); env.socketTextStream("localhost", 8081); // String serviceUrl = "pulsar://10.180.85.1:6650"; // String adminUrl = "http://10.180.85.1:8080";; String serviceUrl = "pulsar://localhost:6650"; String adminUrl = "http://localhost:8080";; // String topic = "public/my-namespace/my-topic"; // String path = "hdfs://10.180.85.1:9000/user/root/paimon/files"; String path = "E:/workspace/algorithum/pulsar17/out"; PulsarSource<String> source = PulsarSource.builder() .setServiceUrl(serviceUrl) .setAdminUrl(adminUrl) .setStartCursor(StartCursor.earliest()) .setTopics("t1/np/to") // .setSubscriptionType(SubscriptionType.Shared) .setDeserializationSchema(PulsarDeserializationSchema.flinkSchema(new SimpleStringSchema())) .setSubscriptionName("my-subscription") .build(); DataStreamSource<String> stream = env.fromSource(source, WatermarkStrategy.noWatermarks(), "Pulsar Source"); stream.print(); DataStream<String> shuffle = stream.shuffle(); final FileSink<String> sink = FileSink .forRowFormat(new Path(path), new SimpleStringEncoder<String>("UTF-8")) .withRollingPolicy( DefaultRollingPolicy.builder() .withRolloverInterval(Duration.ofMinutes(15)) .withInactivityInterval(Duration.ofMinutes(5)) .withMaxPartSize(MemorySize.ofMebiBytes(1024)) .build()) .build(); shuffle.sinkTo(sink); env.execute(); }` 2. I debug the code and find stack will occur this exception all the time:  3. I can promise that there's no other comsumers connect this topic:   ### What did you expect to see? i want to sync data from pulsar to hdfs well ### What did you see instead? see output of the data ### Anything else? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
