hive.ppd.remove.duplicatefilters description is incorrect. What is
the correct one?
I noticed that conf/hive-default.xml.template has the following description
<property>
<name>hive.ppd.remove.duplicatefilters</name>
<value>true</value>
<description>Whether to push predicates down into storage handlers.
Ignored when hive.optimize.ppd is false.</description>
</property>
Most probably the description was taken from "hive.optimize.ppd.storage"
So, what is the correct description for "hive.ppd.remove.duplicatefilters"?

Ping. (Should we open a JIRA issue for this?)

Good catch, Alexander!
hive.ppd.remove.duplicatefilters was added in 0.8.0 by HIVE-1538
<https://issues.apache.org/jira/browse/HIVE-1538> (FilterOperator is
applied twice with ppd on) without any description. It isn't documented in
the wiki yet.
