Found two more from HIVE-5522
https://issues.apache.org/jira/browse/HIVE-5522 (also HIVE-6098
https://issues.apache.org/jira/browse/HIVE-6098, Merge Tez branch into
trunk) so the current total is 51 configs that don't have descriptions in
0.13.0:
*Release 13 *
hive.compute.splits.in.am
hive.rpc.query.plan
But these both have comments in HiveConf.java that can be used as
descriptions, although they aren't included in hive-default.xml.template.
I missed them because I was working from the patch for HIVE-6037
https://issues.apache.org/jira/browse/HIVE-6037 and Navis had used the
HiveConf comments for descriptions. (That means there could be more
parameters missing from the 0.13.0 template file.)

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.]
