Scan DataSource with predicate expression combine partition key and attributes doesn't work

withSQLConf(SQLConf.PARQUET_FILTER_PUSHDOWN_ENABLED.key -> "true") {
      withTempPath { dir =>
        val path = s"${dir.getCanonicalPath}/part=1"
        (1 to 3).map(i => (i, i.toString)).toDF("a", "b").write.parquet(path)

        // If the "part = 1" filter gets pushed down, this query will throw an exception since
        // "part" is not a valid column in the actual Parquet file
        checkAnswer(
          sqlContext.read.parquet(path).filter("a > 0 and (part = 0 or a > 1)"),
          (2 to 3).map(i => Row(i, i.toString, 1)))
      }
    }
