使用 scala 为 geo_point 显式映射

Question

好的，我正在尝试在 Kibana 的索引中生成地理点以使用地图。

这是我的代码：

 import org.apache.spark.{SparkContext, SparkConf}
  import org.elasticsearch.spark._

 object KibanaIndice {

  def main(args: Array[String]) {


val conf = new SparkConf().setAppName("PruebaKibana")
conf.set("es.index.auto.create", "true").set("spark.driver.allowMultipleContexts", "false")

val sc = new SparkContext(conf)


val mapa  = Seq(

  Map("year" -> "2014-01-11","total" -> 123,"aprobadas"->12,"days"->33,"formalizadas"->8, "loca"-> "41.722, -34.456"),
  Map("year" -> "2014-02-11","total" -> 223,"aprobadas"->43,"days"->28,"formalizadas"->22,"loca"-> "42.722, -34.456"),

)


sc.makeRDD(mapa).saveToEs("geolol/geo_point")

}

}

在 loca 中，我尝试传递一个带有坐标的字符串，如文档所述，我假设我必须创建索引来告诉 loca 类型是地理点，但我不知道该怎么做。

谢谢大家。

如果你的索引还没有建立，你必须自己在elasticsearch中创建它，并将"loca"映射为地理类型。这是取自文档的示例：

PUT /attractions
{
  "mappings": {
    "restaurant": {
      "properties": {
        "name": {
          "type": "string"
        },
        "location": {
          "type": "geo_point"
        }
      }
    }
  }
}

默认情况下，它会将您的数字理解为整数并将其索引为它们的数组。
