> StorageHandler PPD query planning statistics not adjusted for pushedPredicate
> -----------------------------------------------------------------------------
>
> 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
> Priority: Minor
>
> 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)
