提交组xxx的偏移时发生错误UNKNOWN_MEMBER_ID

Question

使用Kafka客户端Java库,使用日志已经工作了一段时间但是出现以下错误它不再起作用:

2016-07-15 19:37:54.609  INFO 4342 --- [main] o.a.k.c.c.internals.AbstractCoordinator  : Marking the coordinator 2147483647 dead.
2016-07-15 19:37:54.933 ERROR 4342 --- [main] o.a.k.c.c.internals.ConsumerCoordinator  : Error UNKNOWN_MEMBER_ID occurred while committing offsets for group logstash
2016-07-15 19:37:54.933  WARN 4342 --- [main] o.a.k.c.c.internals.ConsumerCoordinator  : Auto offset commit failed: Commit cannot be completed due to group rebalance
2016-07-15 19:37:54.941 ERROR 4342 --- [main] o.a.k.c.c.internals.ConsumerCoordinator  : Error UNKNOWN_MEMBER_ID occurred while committing offsets for group logstash
2016-07-15 19:37:54.941  WARN 4342 --- [main] o.a.k.c.c.internals.ConsumerCoordinator  : Auto offset commit failed:

它一直在重置.

运行同一应用程序的另一个实例会立即收到错误.

我怀疑Kafka或它的ZooKeeper有问题,但没有错误日志.

谁知道这里发生了什么？

我刚遇到同样的问题.我一直在调查,在这个帖子和这个维基中你可以找到解决方案.

问题似乎是批处理的处理时间比会话超时时间长.增加会话超时或轮询频率或限制接收的字节数.

对我有用的是改变max.partition.fetch.bytes.但您也可以修改session.timeout.ms或传递给您的值consumer.poll(TIMEOUT)
