What's the best way to deal with these?

   1. Ignore them (or identify those that can be ignored).
   2. Add some descriptions in Hive 0.13.0 RC1.
   3. Deal with them after
HIVE-6037<https://issues.apache.org/jira/browse/HIVE-6037>gets
committed.
      - Try to cover all of them by Hive 0.14.0:
      - Put the list in a JIRA and create a common HiveConf.java patch,
         which can be appended until release 0.14.0 is ready.
         - Accumulate descriptions in JIRA comments, then create a patch
         from the comments.
      - Deal with them as soon as possible:
      - Put the list in an umbrella JIRA and use sub-task JIRAs to add
         descriptions individually or in small groups.
         4. Deal with them in the wiki, then patch HiveConf.java before
   release 0.14.0.
   5. [Your idea goes here.]
