Lefty Leverenz commented on HIVE-12470:
---------------------------------------
Doc note: This adds *hive.llap.client.consistent.splits* to HiveConf.java.
(It also changes the default of *hive.llap.daemon.service.hosts* from "" to
null but that won't affect the wiki doc. HIVE-11358 introduced
*hive.llap.daemon.service.hosts* in release 2.0.0, which is the same as this
issue's release.)
The documentation belongs in a new LLAP section of Configuration Properties
that will be created for HIVE-11908.

> Allow splits to provide custom consistent locations, instead of being tied to

> LLAP instances may not run on the same nodes as HDFS, or may run on a subset
> of the cluster.
> Using split locations based on FileSystem locality is not very useful in such
> cases - since that guarantees not getting any locality.
> Allow a split to map to a specific location - so that there's a chance of
> getting cache locality across different queries.
