> Key: IMPALA-11047
> URL: https://issues.apache.org/jira/browse/IMPALA-11047
> Project: IMPALA
> Issue Type: Bug
> Affects Versions: Impala 4.0.0
> Reporter: Riza Suminto
> Assignee: Qifan Chen
> Priority: Major
>
> There is a conflict happening in HdfsScanNode.java vs RuntimeFilterGenerator.java when initializing overlap predicate.
> In HdfsScanNode.java, computeStatsTupleAndConjuncts that init statsTuple_ will not be called because PARQUET_READ_STATISTICS=0.
> [https://github.com/apache/impala/blob/9d61bc4/fe/src/main/java/org/apache/impala/planner/HdfsScanNode.java#L409]
>
> On the other hand, in RuntimeFilterGenerator.java, disable_overlap_filter is set to false without considering what is the value of PARQUET_READ_STATISTICS.
