您好，我在练习"分析网站日志，打造访问地图"项目时遇到了如下错误，麻烦指导下，谢谢！ about ideabook

java.lang.ClassNotFoundException: org.apache.commons.httpclient.protocol.ProtocolSocketFactory ---缺少commons-httpclient-3.0.1的jar

[phodal]

看看这个 elastic/elasticsearch-hadoop#586

你有没有加入相应的 jar 包？

[bitian]

jar包我都加入了，安装的pig0.16.0，将elasticsearch-hadoop下面的jar全部放在pig目录下了。

[phodal]

@bitian

按照 http://stackoverflow.com/questions/17973970/how-to-solve-java-lang-noclassdeffounderror 上的解释，仍然是有可能缺少相应的 jar 包。

[bitian]

你好，这个jar包应当放在那里，我下载下来也放到pig目录下了。

[bitian]

我把jar包加错地方了，现在加上没有这个错误了，但是又出现下面的错误：

@bitian 日志上写着：

Cannot detect ES version - typically this happens if the network/Elasticsearch cluster is not accessible or when targeting a WAN/Cloud instance without the proper setting 'es.nodes.wan.only'

[bitian]

谢谢，我解决了这些问题。

[bitian]

您好，最后还遇到一个问题，是关于country字段没有fielddata属性。如下所示：

应当怎么设置这个属性值，谢谢。
