> Starting Spark 2.0, vectorized decoding is introduced for parquet reading. This feature changes the filter pushdown behavior of parquet reading. Thus, we need to update the out-of-dated description of two external `SQLConf`: `spark.sql.parquet.filterPushdown` and `spark.sql.parquet.enableVectorizedReader`. 
> The code for building `parquetReader` can be slightly simplified for easy maintenance. 
> The current test cases do not verify the behavior when `spark.sql.parquet.filterPushdown` is set to `false`, a test case for improving the test case coverage.
