      Description

      We should fix this to check storage ID uniqueness on datanode startup. If someone has manually edited the storage ID files, or if they have duplicated a directory (or re-added an old disk) they could end up with a duplicate storage ID and not realize it.

      The HDFS-7575 fix does generate storage UUID for each storage, but not checks the uniqueness of these UUIDs.
