Lefty Leverenz commented on HIVE-16383:
---------------------------------------
Doc note: This changes the default value and list of possible values for
*datanucleus.connectionPoolingType* and adds
*datanucleus.connectionPool.maxPoolSize* to HiveConf.java, so the wiki will
need to be updated for release 3.0.0.
* [Configuration Properties -- MetaStore |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-MetaStore]
* [Configuration Properties -- MetaStore -- datanucleus.connectionPoolingType |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-datanucleus.connectionPoolingType]
Added a TODOC3.0 label.
Formatting note: The description of *datanucleus.connectionPool.maxPoolSize*
is 6 lines long but will appear on a single line in the generated template file
because \n wasn't used for line breaks. Can this be fixed?
* [AdminManual Configuration -- hive-site.xml and hive-default.xml.template |
https://cwiki.apache.org/confluence/display/Hive/AdminManual+Configuration#AdminManualConfiguration-hive-site.xmlandhive-default.xml.template]
