弹性搜索Spark错误 [英] ElasticSearch Spark Error

问题描述

我是ElasticSearch的新手，我正在尝试编写一些Apache Spark代码来将一些数据保存到ElasticSearch中。我已经进入SparkShell的以下行：

I am new to ElasticSearch and I am trying to write some Apache Spark code to save some data into ElasticSearch. I have entered the following lines into SparkShell:

 import org.elasticsearch.spark._
 val myMap = Map("France" -> "FRA", "United States" -> "US")
 val myRDD = sc.makeRDD(Seq(myMap))
 myRDD.saveToEs("Country/Abbrv")

错误：

 org.elasticsearch.hadoop.EsHadoopIlegalArgumentException:  Cannot determine write shards for [Country/Abbrv]; likely its format is incorrect (maybe it contains illegal characters?)

Spark 2.0.0
ElasticSearch-Spark 2.3.4

Spark 2.0.0 ElasticSearch-Spark 2.3.4

任何想法？

推荐答案

问题是我没有在启动spark shell之前设置--conf var。它需要如下所示：

The issue was that I did not set the --conf var before launching spark shell. It needs to look like the following:

 spark-shell --jars {path}/elasticsearch-spark_2.11-2.3.4.jar --conf spark.es.resource=Country/Abbrv
