Consumer消费数据失败，提示“SchemaException: Error reading field”

问题背景与现象

Consumer来消费Kafka中指定Topic的消息时，发现无法从Kafka中获取到数据。

提示如下错误：

org.apache.kafka.common.protocol.types.SchemaException: Error reading field 'brokers': Error reading field 'host': Error reading string of length 28271, only 593 bytes available

可能原因

客户端和服务端Jar版本不一致。

解决办法

修改Consumer应用程序中Kafka jar，确保和服务端保持一致。
