をリバランスすることができませんでしたが、私は、トピックを作成し、私はそのトピック例外：
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
私はカフカの流れで、以下の簡単な例を実行していますし、私は私が扱うことができない奇妙な例外が発生しました
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();

私はこの例外を何とかしました。私はUbuntuでvmwareのkafkaクラスタを実行しています（私が使用しているバージョンはkafka_2.11-0.10.0.0です）おそらく問題はRAM-Cpuですか？
神はあなたを祝福!!!!!! –
