Process residual predicate during automatic index query
-------------------------------------------------------
Key: HIVE-2115
URL: https://issues.apache.org/jira/browse/HIVE-2115
Project: Hive
Issue Type: Improvement
Components: Indexing
Affects Versions: 0.8.0
Reporter: Russell Melick
During automatic use of indexes, we analyze the query predicate to pull out
what we can use the index on. Not all of the predicate can necessarily be
processed with a single index. Currently, we return the residual predicate
from the IndexHandler but do not process it further. We run the full original
predicate on the index table. Ideally, we would want to only run the residual
predicate so we don't have to do as much processing.
