我在Spark上创建了一个Master和一个Worker。然后，我创建了一个Spark流作业，并尝试提交它，但是在Master上，它显示了很长的Java错误列表
使用此命令启动主服务器：
使用它来启动工作程序：
要提交火花作业，请尝试使用具有不同参数的命令：

答案 0 :(得分：1)
类似
的错误java.lang.IllegalArgumentException: Unsupported class file major version 56
表示该类是在比我们尝试运行它的版本更高的Java版本上编译的。
v56表示您使用Java 12进行编译，并且我不知道您的Spark使用哪个Java版本。根据这张票证，Spark似乎还与Java 11不兼容：https://issues.apache.org/jira/browse/SPARK-24417
解决方案是使用jdk的早期版本编译代码。
