elasticsearch - 将Elasticsearch jriver jdbc插件与索引设置一起使用时发生错误

Question

我正在尝试将elasticsearch jdbc jriver插件与自定义index_settings一起使用，但似乎无法创建索引。这是我的字符串:

    # search channels
PUT /_river/tetours/_meta
{
   "type": "jdbc",
   "jdbc": {
      "driver": "com.mysql.jdbc.Driver",
      "url": "jdbc:mysql://localhost:3306/test",
      "user": "blah",
      "password": "******",
      "sql": "SELECT id AS _id,title,city FROM channel where active=1",
      "strategy": "simple",
      "autocommit": true,
      "index": "teindex",
      "type": "tours",
      "index_settings" : "{ \"analysis\" : { \"analyzer\": { \"tindex_analyzer\": { \"tokenizer\": \"standard\", \"filter\": [\"standard\",\"lowercase\"]},\"tsearch_analyzer\": {\"tokenizer\": \"standard\",\"filter\": [\"standard\",\"synonym\",\"lowercase\"]}}, \"filter\" : { \"synonym\" : { \"type\" : \"synonym\", \"synonyms_path\" : \"analysis/synonym.txt\" }}}}",
      "type_mapping": "{ \"tours\": {\"properties\": {\"title\": {  \"type\": \"string\",\"index\": \"analyzed\", \"index_analyzer\": \"tindex_analyzer\", \"search_analyzer\": \"tsearch_analyzer\", \"store\": \"yes\"}}}}",     
      "poll": "15m"
   }
}

这是我在日志文件中收到的错误消息:

谁能找出问题所在？语法看起来正确。

Answer 1

您不能在实时索引上写入这些类型的设置(过滤器，分析器等)。您必须关闭索引，进行更改，然后再次打开

乍一看JDBCRiver的代码并没有显示任何简单的方法来处理它。
