> -------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-16010
> URL: https://issues.apache.org/jira/browse/SPARK-16010
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
>
> 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.
