Description
IMPALA-11123 add assertion to verify NumFileMetadataRead in parquet-stats-agg.test. We found that in the multiblock test, the number of NumFileMetadataRead can differ in erasure coding configuration. This is most likely because erasure coded setup create less files. Below is the stack trace:
