import org.apache.hadoop.fs.FileContextTestHelper; //导入方法依赖的package包/类
static public FileContext setupForViewFsLocalFs(FileContextTestHelper helper) throws Exception {
/**
* create the test root on local_fs - the mount table will point here
*/

// the test path may be relative to working dir - we need to make that work:
// Set up viewfs link for wd as described above
