为JDBC Elasticsearch River设置映射

Question

我正在将ES 0.20.6与elasticsearch -river-
jdbc插件一起使用
。我使用以下方法创建了一条河：

SQL="SELECT ..."
curl -XPUT 'localhost:9200/_river/myindex_river/_meta' -d '{
    "type" : "jdbc",
    "jdbc" : {
        "driver" : "org.postgresql.Driver",
        "url" : "jdbc:postgresql://localhost:5432/mydb_db",
        "user" : "myuser",
        "password" : "mypassword",
        "sql" : "'"$SQL"'"
    },
    "index" : {
        "index" : "myindex",
        "type" : "mytype",
        "type_mapping" : null
    }
}'

现在，我要添加的类型映射为插件文档中定义的选项。但我真的无法弄清楚语法，总是会收到以下错误（"Source: "部分内容因我的尝试而异）

我认为您提交的东西甚至都不是正确的json对象。我可以想象到type_mapping对象必须包含映射，与使用put映射api或创建索引所提交的映射几乎相同。
