我正在使用 spring kafka 并面临一些错误
Error sending fetch request (sessionId=INVALID, epoch=INITIAL) to node 1001: org.apache.kafka.common.errors.DisconnectException.给出了我的消费者生产者代码
@EnableKafka

我不确定我做错了什么。 我正在使用
org.apache.avro:1:8:2io.confluent.kafka-avro-serializer:3.2.1正如 @Ahmad Abdelghany 评论所说，设置
org.apache.kafkaDEBUG org.apache.kafka.clients.NetworkClient - Disconnecting from node 1 due to request timeout.
DEBUG org.apache.kafka.clients.consumer.internals.ConsumerNetworkClient - Cancelled request with header RequestHeader(apiKey=FETCH, apiVersion=11, clientId=consumer-1, correlationId=183) due to node 1 being disconnected
DEBUG org.apache.kafka.clients.NetworkClient - Give up sending metadata request since no node is available
INFO org.apache.kafka.clients.FetchSessionHandler - Error sending fetch request (sessionId=INVALID, epoch=INITIAL) to node 1: {}.
org.apache.kafka.common.errors.DisconnectException: null
DEBUG org.apache.kafka.clients.NetworkClient - Give up sending metadata request since no node is available
重要的一点是：
由于请求超时
您可以使用
增加
request.timeout.ms（默认 30000）
props.put(ConsumerConfig.REQUEST_TIMEOUT_MS_CONFIG, "60000");
注意：您的情况应该有所不同，因为您的超时设置为 10 分钟。显示调试日志应该会有所帮助。
我也有类似的问题。就我而言，它发生了，因为 kafka 在
connections.max.idle.ms我在消费者日志中有下一条消息：

因此，请尝试减少消费者配置中的
fetch.max.wait.msconnections.max.idle.ms
