      Description

      There are some opportunities inside HDFS where we can use DNS for hosts instead of host names. This will help to a large extent in two aspects:
      1. Server management, i.e. host replacement
      2. Client transparency, i.e. client config with DNS without knowing the specific host.

      It is worth mentioning that secure environment should be supported, we recommend having the principal wildcard matching turned on.
