-------------------------------
Summary: StorageHandler PPD query planning statistics not adjusted
for residualPredicate
Key: HIVE-27149
URL: https://issues.apache.org/jira/browse/HIVE-27149
Project: Hive
Issue Type: Bug
Components: StorageHandler
Affects Versions: 4.0.0-alpha-2
Reporter: Yi Zhang
In StorageHandler PPD, filter predicates can be pushed down to storage and
trimmed to a subset residualPredicate, however, at query planning statistics
based on filters only consider the 'final' residual predicates, when in fact
there are pushedPredicates that should also be considered, this affect reducer
parallelism (more reducers than needed)
