Lefty Leverenz commented on HIVE-10040:
---------------------------------------
Doc note: This adds *hive.cbo.costmodel.extended* to HiveConf.java, so it will
need to be documented in the wiki when cbo-branch merges to trunk. Should it
be mentioned in the CBO design doc as well as the Configuration Properties?
* [Cost-based optimization in Hive |
https://cwiki.apache.org/confluence/display/Hive/Cost-based+optimization+in+Hive]
* [Configuration Properties |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties]
** could put it next to [hive.cbo.enable |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.cbo.enable]

> model should be integrated within a Calcite MD provider that is pluggable.
