at java.lang.Thread.run(Thread.java:748) [?:1.8.0_291]从异常信息知是jar包版本导致的，因为Javalin requires javax.servlet version 3.1.0
这里我们介绍一下两种解决方式

2.maven shade
代码语言：javascript复制<relocation>
<pattern>javax.servlet.</pattern>
<shadedPattern>${flink.bundle.shade.prefix}javax.servlet.</shadedPattern>
</relocation>该改动已经提交给社区[HUDI-2557]https://github.com/apache/hudi/pull/3807
