Lefty Leverenz commented on HIVE-14731:
---------------------------------------
Doc note: This adds *hive.tez.cartesian-product.enabled* to HiveConf.java, so
it needs to be documented in the wiki.
* [Configuration Properties -- Tez |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Tez]
Added a TODOC3.0 label.
Also, [~hagleitn] please update the status and fix version.
> Use Tez cartesian product edge in Hive (unpartitioned case only)

> Given cartesian product edge is available in Tez now (see TEZ-3230), let's
> integrate it into Hive on Tez. This allows us to have more than one reducer
> in cross product queries.
