    Description

      After HDFS-12681, HdfsFileStatus#getPath() returns null.
      I don't think this is expected.

      Both the implementation of HdfsFileStatus sets the path to null.

      HdfsNamedFileStatus.java
        HdfsNamedFileStatus(long length, boolean isdir, int replication,
                            long blocksize, long mtime, long atime,
                            FsPermission permission, Set<Flags> flags,
                            String owner, String group,
                            byte[] symlink, byte[] path, long fileId,
                            int childrenNum, FileEncryptionInfo feInfo,
                            byte storagePolicy, ErasureCodingPolicy ecPolicy) {
          super(length, isdir, replication, blocksize, mtime, atime,
              HdfsFileStatus.convert(isdir, symlink != null, permission, flags),
              owner, group, null, null,           ------ The last null is for path.
              HdfsFileStatus.convert(flags));
      
      HdfsLocatedFileStatus.java
        HdfsLocatedFileStatus(long length, boolean isdir, int replication,

                              FsPermission permission, EnumSet<Flags> flags,
                              String owner, String group,
                              byte[] symlink, byte[] path, long fileId,
                              int childrenNum, FileEncryptionInfo feInfo,
                              byte storagePolicy, ErasureCodingPolicy ecPolicy,
                              LocatedBlocks hdfsloc) {
          super(length, isdir, replication, blocksize, mtime, atime,
              HdfsFileStatus.convert(isdir, symlink != null, permission, flags),
              owner, group, null, null, HdfsFileStatus.convert(flags),  -- The last null on this line is for path.
              null);
