Code to reproduce:

val dataSourceName = "parquet" 
val path = "/home/fejiang/Desktop"
spark.conf.set("spark.sql.parquet.enableVectorizedReader", "true")
val schema = ("`id` INT,`name` STRUCT<`first`: STRING, `middle`: STRING, `last`: STRING>, " +
  "`address` STRING,`pets` INT,`friends` ARRAY<STRUCT<`first`: STRING, `middle`: STRING, " +
  "`last`: STRING>>,`relatives` MAP<STRING, STRUCT<`first`: STRING, `middle`: STRING, " +
  "`last`: STRING>>,`employer` STRUCT<`id`: INT, `company`: STRUCT<`name`: STRING, " +
  "`address`: STRING>>,`relations` MAP<STRUCT<`first`: STRING, `middle`: STRING, " +
  "`last`: STRING>,STRING>,`p` INT")
spark.read.format(dataSourceName).schema(schema).load(path + "/contacts").createOrReplaceTempView("contacts")

 val query = spark.sql("select name.middle from contacts where p=2")
query.show()

Spark:

scala> val dataSourceName = "parquet" 
dataSourceName: String = parquet

     |   "`last`: STRING>>,`employer` STRUCT<`id`: INT, `company`: STRUCT<`name`: STRING, " +
     |   "`address`: STRING>>,`relations` MAP<STRUCT<`first`: STRING, `middle`: STRING, " +

schema: String = `id` INT,`name` STRUCT<`first`: STRING, `middle`: STRING, `last`: STRING>, `address` STRING,`pets` INT,`friends` ARRAY<STRUCT<`first`: STRING, `middle`: STRING, `last`: STRING>>,`relatives` MAP<STRING, STRUCT<`first`: STRING, `middle`: STRING, `last`: STRING>>,`employer` STRUCT<`id`: INT, `company`: STRUCT<`name`: STRING, `address`: STRING>>,`relations` MAP<STRUCT<`first`: STRING, `middle`: STRING, `last`: STRING>,STRING>,`p` INT

scala> spark.read.format(dataSourceName).schema(schema).load(path + "/contacts").createOrReplaceTempView("contacts")

scala> 

scala>  val query = spark.sql("select name.middle from contacts where p=2")
query: org.apache.spark.sql.DataFrame = [middle: string]

scala> query.show()
