Solve the problem of long type when scala calls api to operate elasticsearch

When writing a spark program in scala, in order to facilitate control, the java api will be called to operate elasticsearch. At this time, a map is needed to receive specific fields. There is a problem here, that is, the accepted map must be of type AnyRef , For example, we need to store a value of type long, such as time is a long, then there will be a problem with direct writing, because AnyRef in scala does not contain a numerical type, but belongs to the AnyVal type. In this case, we use the following method to force conversion to solve this problem

val map=scala.collection.mutable.Map[String,AnyRef]()

    map.put("age","26".toLong.asInstanceOf[AnyRef])

    map.put("name","ll")

    val map2=scala.collection.JavaConversions.mutableMapAsJavaMap(map)

    val indexRequest = new IndexRequest("hyj2017", "test","bbb").source(map2)
    proos.add(indexRequest)


    proos.awaitClose(10, TimeUnit.SECONDS);
    client.close()
