1、报错:: java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.NotLeaderForPartitionException: This server is not the leader for that topic-partition.
报错原因:producer在向kafka broker写的时候,刚好发生选举,本来是向broker0上写的,选举之后broker1成为leader,所以无法写成功,就抛异常了。
解决办法:修改producer的重试参数retries参数,默认是0, 一般设置为3, 我在生产环境配置的retries=10
2、java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.TimeoutException: Expiring 1 record(s) for binlogCsbbroker-2 due to 30026 ms has passed since batch creation plus linger time
报错原因:具体原因我自己还没有找到,但是网友们都说是因为kafka在批量写的时候,这一批次的数据没有在30s内还处理完,(30s为request.timeout.ms默认值),这一批次的数据就过期了,所以抛出异常
解决办法:增大request.timeout.ms, 我在生产环境配置的是request.timeout.ms=60000 // 由原来默认的30s改成60s
3、java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.NetworkException: The server disconnected before a response was received.
报错原因:kafka client与broker断开连接了
解决办法:重启服务
