    Description

      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.

      On the other hand, in RuntimeFilterGenerator.java, disable_overlap_filter is set to false without considering what is the value of PARQUET_READ_STATISTICS.
