[SPARK-23604][SQL] Change Statistics.isEmpty to !Statistics.hasNonNul⦠â¦lValue ## What changes were proposed in this pull request? Parquet 1.9 will change the semantics of Statistics.isEmpty slightly to reflect if the null value count has been set. That breaks a timestamp interoperability test that cares only about whether there are column values present in the statistics of a written file for an INT96 column. Fix by using Statistics.hasNonNullValue instead. ## How was this patch tested? Unit tests continue to pass against Parquet 1.8, and also pass against a Parquet build including PARQUET-1217.
