Lefty Leverenz commented on HIVE-1538:
--------------------------------------
Doc note: This added *hive.ppd.remove.duplicatefilters* to HiveConf.java. It
needs to be documented in the wiki.
* [Configuration Properties |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties]
It also needs an appropriate description, as [~apivovarov] pointed out in a
message to the dev@hive mailing list:
* ["hive.ppd.remove.duplicatefilters description is incorrect. What is the
correct one?" |
