下载elasticsearch的spark相关包 https://www.elastic.co/downloads/hadoopimport org.elasticsearch.spark._import org.elasticsearch.spark.sql._import org.apache.spark.SparkConfimport org.apache.spark.SparkCon

假定你已经安装了elasticsearch2.1.0和maven, 下面的步骤针对elasticsearch2.1.0有效, 其它版本可能不使用下载ik因为我的elasticsearch是2.1.0,所以去这里下载https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v1.6.1其它版本的elasticsearch对应的ik去

下载jar包 https://www.elastic.co/downloads/hadoop将elasticsearch-spark_2.10-2.4.0.jar加入类路径里面 import org.elasticsearch.spark.sql._ // DataFrame schema automatically inferred val conf

curl 'localhost:9200/_cat/indices?v'

首先参考https://github.com/NLPchina/elasticsearch-sql 有的时候使用上述url中介绍的安装方式安装不上，这个时候就需要手动安装了。 1.下载es-sql 比如我使用的es的版本是2.3.3 https://github.com/NLPchina/elasticsearch-sql/releases/download/2.3.3.0/elastics

先参考https://yq.aliyun.com/articles/60517 编译完之后需要经jar包加入到你的项目还需要三个依赖： <dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId>

静态模板 https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-templates.html动态模板PUT /_template/product{ "order": 0, "template": "product*_*", "mappings": { "_default_": {

PUT/music/_mapping/song{ “properties”: { “tag”: { “type”: “string”, “index”: “not_analyzed”, “doc_values”: true } }}这个就会使用磁盘存储这个字段，而不是存储在内存中

index.query.default_field 可以设置默认搜索的字段。详细参考http://stackoverflow.com/questions/10518404/in-elasticsearch-should-we-use-default-field-in-query-string-for-ngram-analyzerindex.mapping.ignore_malformed：全局设置i

使用特定analyzer分析文本curl -XGET 'localhost:9200/_analyze' -d '{ "analyzer" : "standard", "text" : "this is a test"}上边最后可能少了一个单引号使用某个字段的分析器分析文本,这里分别使用tag和tweethttp://es.xiaoleilu.com/052_Mapping_Analys
