      Description

      See HDFS-487.
      Even though that is resolved as duplicate, the ID is actually not exposed by the JIRA it supposedly duplicates.
      INode ID for the file should be easy to expose; alternatively ID could be derived from block IDs, to account for appends...

      This is useful e.g. for cache key by file, to make sure cache stays correct when file is overwritten.
