-------------------------------------
Summary: Allow splits to provide custom consistent locations,
instead of being tied to data locality
Key: HIVE-12470
URL: https://issues.apache.org/jira/browse/HIVE-12470
Project: Hive
Issue Type: Improvement
Components: llap
Reporter: Siddharth Seth
Assignee: Siddharth Seth
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.
