Lefty Leverenz commented on HIVE-1511:
--------------------------------------
*hive.plan.serialization.format* is documented in the wiki here:
* [Configuration Properties -- hive.plan.serialization.format |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.plan.serialization.format]
The release note ("Any 3rd party UDFs used must be declared as public classes")
could be added to these wikidocs:
* [Hive Plugins -- Creating Custom UDFs |
https://cwiki.apache.org/confluence/display/Hive/HivePlugins#HivePlugins-CreatingCustomUDFs]
* [DDL -- Create Function |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateFunction]
Question: Does the release note apply in general, or only in releases 0.13.0
and later?
