运行Kafka服务器会引发NoClassDefFoundError异常

Question

我在运行的Kafka服务器中收到很多NoClassDefFoundError信息。我不确定是什么原因造成的？还有其他人遇到过这个问题吗？

我正在使用Kafka v2.1.1和Java11。我最近升级到v2.1.1

更新： 请注意，在整个集群的5个经纪人中，只有2个经纪人会看到此异常。

例外1：

+-------------+---------+
| "Banana"    | ""      |
| "~A Apple"  | "One"   |
| "~B Orange" | "Two"   |
| "Banana ~C" | "Three" |
| "Apple ~CC" | "Four"  |
+-------------+---------+
