Persistent view stored in Hive metastore should be case preserving.

    withView("view1") {
      spark.sql("CREATE VIEW view1 AS SELECT 1 AS cAsEpReSeRvE, 2 AS aBcD")
      val metadata = new MetadataBuilder().putString(types.HIVE_TYPE_STRING, "int").build()

      val expectedSchema = StructType(List(
        StructField("cAsEpReSeRvE", IntegerType, nullable = false, metadata),
        StructField("aBcD", IntegerType, nullable = false, metadata)))
      assert(spark.table("view1").schema == expectedSchema, "Schema should match")
      checkAnswer(
        sql("select aBcD, cAsEpReSeRvE from view1"),
        Row(2, 1))
    }
