Scala IgniteRDD不返回数据帧中的行

我正在IgniteRDD上执行sql查询。对于RDD转换和操作，它运行正常，但是当我在IgniteRDD上调用sql时，它不会返回任何结果。这是我写的确切代码

private val conf = new SparkConf()
.setAppName("IgniteRDDExample")
.setMaster("local")
.set("spark.executor.instances", "2")

  /** Spark context */
  val sparkContext = new SparkContext(conf)

  /** Defines spring cache Configuration path */
  private val CONFIG = "examples/config/example-shared-rdd.xml"

  /** Creates Ignite context with above configuration configuration */
  val igniteContext = new IgniteContext(sparkContext, CONFIG, false)

  /** Creates an Ignite RDD of Type (Int,Int) Integer Pair */
  val sharedRDD: IgniteRDD[Int, Int] = igniteContext.fromCache[Int, Int]("sharedRDD")

  /** Fill IgniteRDD with Int pairs */
  sharedRDD.savePairs(sparkContext.parallelize(1 to 1000, 10).map(i => (i, i)))

  /** Transforming Pairs to contain their Squared value */
  sharedRDD.mapValues(x => (x * x))

  /** Retrieve sharedRDD back from the Cache */
  val transformedValues: IgniteRDD[Int, Int] = igniteContext.fromCache[Int, Int]("sharedRDD")

  transformedValues.take(5).foreach(println)

  /** Performing SQL query on existing cache and
    * collect result into a Spark Dataframe
    * */

  val rs = transformedValues.sql("select * from Integer where number > ? and number < ? ", 10, 100)
  /** Show DataFrame results */
  println("The count is::::::::::: "+rs.count)

这里的action.take5在转换后的值上返回结果并打印它。但当我在上面运行sql方法时，它返回0作为行计数。我不知道。请帮忙

以下是我的缓存配置设置：

Integer类中没有数字字段，因此从SQL的角度来看它总是空的。将基本体用作键和/或值时，可以使用预定义的_key和_val字段。因此，查询可以如下所示：

select * from Integer where _val > ? and _val < ?

---

在这种情况下，也没有太多理由使用queryEntities。setIndexedTypes足够简单了。

我将查询更改为从整数中选择*，结果数据框中仍然有0条记录。缓存的配置是否仍有错误？
