Lefty Leverenz commented on HIVE-12623:
---------------------------------------
Doc note: This adds *hive.llap.task.scheduler.locality.delay* to HiveConf.java
so it needs to be documented in the wiki for 2.0.0 (in a new section for LLAP
parameters, to be created for HIVE-9850 and HIVE-11908).
* [Hive Configuration Properties |

> Add an option to force allocation of fragments on requested nodes

> Currently, fragments are sent to random nodes if the requested node does not
> have capacity. In certain situations there's more to be gained by sending the
> fragments to the requested node only.
