Lefty Leverenz commented on HIVE-1511:
--------------------------------------
This patch adds hive.plan.serialization.format to HiveConf.java and
hive-default.xml.template, so I'll put it in the wiki for Hive 0.13.0.
The release note ("Any 3rd party UDFs used must be declared as public classes")
should probably go in the wiki somewhere too.
