У меня есть один узел Kafka-2.11, установленный в экземпляре EC2, группа безопасности настроена правильно, порты доступны с моего локального компьютера с помощью команды telnet.
from pykafka import KafkaClient
kafka_host = 'X.X.X.X:9092'
client = KafkaClient(kafka_host)
print(client.topics)
topic = client.topics["test"]
producer = topic.get_producer(sync=True)
producer.produce(b"your message")
Получается список всех тембез каких-либо ошибок.
Кроме того, когда я вхожу в экземпляр EC2 и создаю производителя и потребителя через CLI или через python, это работает нормально.Но на моем локальном компьютере, когда я пытаюсь опубликовать сообщение через PyKafka для брокера Kafka в EC2, он выдает мне следующую ошибку:
SocketDisconnectedError Traceback (most recent call last) <ipython-input-10-0bfe24be5251> in <module>
