[jira] [Created] (SPARK-16400) Remove InSet filter pushdown from Parquet

Reynold Xin created SPARK-16400:
-----------------------------------

             Summary: Remove InSet filter pushdown from Parquet
                 Key: SPARK-16400
                 URL: https://issues.apache.org/jira/browse/SPARK-16400
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Reynold Xin


Filter pushdown that needs to be evaluated per row is not useful to Spark, since parquet-mr own filtering is likely to be less performant than Spark's due to boxing and virtual function dispatches.

To simplify the code base, we should remove the InSet filters.
