1. 索引名称错误
1.1 代码
xiaosi@Qunar:~$ curl -XPUT 'localhost:9200/Quanr/employee/1' '> {> "first_name" : "John",> "last_name" : "Smith",> "age" : 25,> "about" : "I love to go rock climbing",> "interests": [ "sports", "music" ]> }';{"error":{"root_cause":[{"type":"invalid_index_name_exception","reason":"Invalid index name [Quanr], must be lowercase","index":"Quanr"}],"type":"invalid_index_name_exception","reason":"Invalid index name [Quanr], must be lowercase","index":"Quanr"},"status":400}curl: (3) [globbing] nested brace in column 148
1.2 报错原因
索引名称必须小写
1.3 解决方案
xiaosi@Qunar:~/opt/elasticsearch-2.3.3$ curl -XPUT 'localhost:9200/qunar-index/employee/1' -d '> {> "first_name" : "John",> "last_name" : "Smith",> "age" : 25,> "about" : "I love to go rock climbing",> "interests": [ "sports", "music" ]> }';{"_index":"qunar-index","_type":"employee","_id":"1","_version":1,"_shards":{"total":2,"successful":1,"failed":0},"created":true}xiaosi@Qunar:~/opt/elasticsearch-2.3.3$
2. 使用Groovy脚本更新文档报错
2.1 代码
/*** 使用脚本更新文档* @param client* @param index* @param type* @param id*/public static void updateByScripted(Client client, String index, String type, String id){UpdateRequestBuilder updateRequestBuilder = client.prepareUpdate();updateRequestBuilder.setIndex(index);updateRequestBuilder.setType(type);updateRequestBuilder.setId(id);// 脚本Script collegeScript = new Script("ctx._source.college = \"软件学院\"", ScriptService.ScriptType.INLINE, null, null);updateRequestBuilder.setScript(collegeScript);// 更新文档UpdateResponse response = updateRequestBuilder.get();}
2.2 报错信息

2.3 报错原因
脚本默认被禁用了。https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting.html
2.4 解决方案
在安装目录下config文件夹找到elasticsearch.yml文件，然后添加如下配置：
script.engine.groovy.inline.update: on
然后重新启动ElasticSearch
