我正在尝试使用以下代码片段以编程方式在Elasticsearch中创建索引：
String indexName = "index";
String indexJson = createIndexJson();
elasticsearchTemplate.createIndex(indexName, indexJson);
createIndexJson()返回以下字符串：
{
"mappings": {
"video": {
"properties": {
"title": {
"properties": {
"en": {
"type": "text",
"analyzer": "english"
}
}
},
"desc": {
"properties": {
"en": {
"type": "text",
"analyzer": "english"
}
}
}
}
}
}
}
elasticsearchTemplate创建为：
new ElasticsearchTemplate(
new PreBuiltTransportClient(Settings.EMPTY)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300)));
如果我运行此代码，我会收到以下异常：
java.lang.IllegalArgumentException: unknown setting [index.mappings.video.properties.desc.properties.en.analyzer] please check that any required plugins are installed, or check the breaking changes documentation for removed settings

所以基本上它抱怨索引定义的这一部分：
"en": {
"type": "text",
"analyzer": "english"
}
如果我使用相同的索引定义并使用它来使用Elasticsearch REST API PUT localhost:9200/index创建索引，那么Elasticsearch 5.6.6和Elasticsearch 6.2.1都可以正常工作
我注意到，由于此代码请求不会转到Elasticsearch服务器，因此显然它们无法在客户端验证。
这种验证失败的原因是什么？我是否需要在Elasticsearch客户端配置中添加插件？
