Problem solving

From the bug printed on the console, it seems that there are illegal characters in the java file executed during startup, resulting in startup failure. After repeated search, we can’t find which java file he started has an error,

Try to reduce the version and start successfully after using spark-3.1.2-bin-hadoop 3.2

It may be that the configuration of the higher version has changed and the understanding is not deep. 0.0
