Exception in thread “StreamThread-1” org.apache.kafka.streams.errors.StreamsException: Failed to rebalance

Question

I created a topic and i put a simple-producer to publish some message in that topic

 bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic streams-file-input

bin/kafka-console-producer.sh --broker-list localhost:9092 --streams-file-input

I am running the below simple example in kafka streams and i got a weird exception which i cannot handle

 Properties props = new Properties();
            props.put(StreamsConfig.APPLICATION_ID_CONFIG, "streams-pipe");
            props.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, "192.168.1.3:9092");
            props.put(StreamsConfig.KEY_SERDE_CLASS_CONFIG, Serdes.String().getClass());
            props.put(StreamsConfig.VALUE_SERDE_CLASS_CONFIG, Serdes.String().getClass());

            // setting offset reset to earliest so that we can re-run the demo code with the same pre-loaded data
            props.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest");

            KStreamBuilder builder = new KStreamBuilder();

            builder.stream("streams-file-input").to("streams-pipe-output");

            KafkaStreams streams = new KafkaStreams(builder, props);
            streams.start();

            // usually the stream application would be running forever,
            // in this example we just let it run for some time and stop since the input data is finite.
            Thread.sleep(5000L);

            streams.close();

Whatever i did i got this exception. I am running kafka cluster in vmware with Ubuntu(the version i use is ) Maybe the problem is the ram-Cpu? ）也许问题是ram-Cpu？

Answer 1

Caused by: java.io.FileNotFoundException: C:\tmp\kafka-streams\my-streapplication\0_0\.lock (The system cannot find the path specified)

it means that the parent directory C:\\tmp\\kafka-streams for your application state does not exsist. It is a default directory in StreamConfig . I don't know why it's created failed on Windows.

You can set StreamConfig.STATE_DIR_CONFIG as a specified directory.

Answer 2

thanks to @Muyoo this is the correct fix:

        Properties props = new Properties();
        props.put(StreamsConfig.APPLICATION_ID_CONFIG,"my-stremapplication");
        props.put(StreamsConfig.STATE_DIR_CONFIG, "streams-pipe");
        props.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, "192.168.1.210:9092");
        props.put(StreamsConfig.KEY_SERDE_CLASS_CONFIG, Serdes.String().getClass());
        props.put(StreamsConfig.VALUE_SERDE_CLASS_CONFIG, Serdes.String().getClass());
