Cause of the problem: the literal meaning is that some methods of filesystem (Getscheme, etc.) are not implemented, mainly because of the Hadoop-hdfs Jar package conflict (the Hadoop-hdfs jar package that was called did not find the method)

Workaround: Maven pom.xml file, select "Dependency Hierarchy", enter "Hadoop-hdfs", See which jar packages have introduced Hadoop-hdfs-xxx.jar, and see if there are getscheme in these hadoop-hdfs-xxx.jar, and if not, this Hadoop-hdfs-xxx.jar may be the package that caused the conflict, and the comment avoids the jar Package conflicts
