> It is still possible to read corrupt Parquet's statistics.
> This problem was found in PARQUET-251 and we disabled filter pushdown on binary columns
in Spark before.
> We enabled this after upgrading Parquet but it seems there are potential incompatibility
for Parquet files written in lower Spark versions.
