Description
Follow up to #25448
While exchange FileSystem is a singleton instance which use
fs.defaultFSincore-site.xmlas default uri, so when use other hadoop-compatible file system，we should configfs.defaultFSto match hadoop-compatible file system. eg: we wan't use oss, thefs.defaultFSwould be configured asoss://xxxxincore-site.xml. Therefore, I think we should add some hints in the documentation.Additional context and related issues
