kafka broker调整log.setment.bytes之后报RecordBatchTooLargeException: The request included message batch larger than the configured segment size on the server.

kafka broker的配置参数有一个log.segment.bytes指的是单个日志文件存储的消息容量的最大值，该值最小是14bytes，测试时将该值设成了14，按道理小于14bytes的消息应该仍能写入日志文件，但是输入了一个跟小的值，还是报了异常，这是为什么?

测试日志如下

kafka_2.13-3.4.0$ bin/kafka-console-producer.sh --broker-list ip:port --topic test-segment
