      Description

      ViewFS doesn't validate the mount table mapping. Even the mapped directory on NameNode doesn't exist, list directories or "dfs -ls" command can still show the mapped directory.

      This confuses users and applications when they try to create files under the mapped directories. They will get file-not-exist error but viewfs shows the directory exists.

      It would be less misleading if ViewFS can validate the mount table and report found errors.
