             Summary: Fix TestViewFileSystemOverloadSchemeHdfsFileSystemContract#testListStatusRootDir
                 Key: HDFS-15396
                 URL: https://issues.apache.org/jira/browse/HDFS-15396
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Ayush Saxena
            Assignee: Ayush Saxena


Exception :

{code:java}
java.lang.IllegalArgumentException: Can not create a Path from an empty string
	at org.apache.hadoop.fs.Path.checkPathArg(Path.java:172)
	at org.apache.hadoop.fs.Path.<init>(Path.java:184)
	at org.apache.hadoop.fs.viewfs.ViewFileSystem$InternalDirOfViewFs.listStatus(ViewFileSystem.java:1207)
	at org.apache.hadoop.fs.viewfs.ViewFileSystem.listStatus(ViewFileSystem.java:514)
	at org.apache.hadoop.fs.FileSystemContractBaseTest.assertListStatusFinds(FileSystemContractBaseTest.java:867)
	at org.apache.hadoop.fs.viewfs.TestViewFileSystemOverloadSchemeHdfsFileSystemContract.testListStatusRootDir(TestViewFileSystemOverloadSchemeHdfsFileSystemContract.java:119)
{code}

The reason for failure being, the mount destination for /user and /append in the test is just the URI, with no further path.

Thus while listing, in order to fetch the permissions, the destination URI is used to get the path, which resolves being empty. Hence the failure
