Sergey Shelukhin commented on HIVE-12470:
-----------------------------------------
Can you post a RB?
Why not store the list pre-sorted instead of sorting every time?
Also, what is the need for the cache of registries by name?
> Allow splits to provide custom consistent locations, instead of being tied to
> data locality

> 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.
