             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.
