将mongodb数据移至Elasticsearch

Question

我正在尝试将数据从mongodb移至elasticsearch。

curl -XPUT "localhost:9200/myindex/river/_meta" -d '{
 "type": "mongodb",
 "mongodb": {
"servers": [
  {
    "host": "127.0.0.1",
    "port": 27017
  }
],
"options": {
  "secondary_read_preference": true
},
"db": "handmade",
"collection": "logData"
  },
 "index": {
"name": "myindex",
"type": "classdata"
  }}' -H 'Content-Type: application/json'

但是，代码内容按原样插入。

type:mongodb mongodb.servers:{ "host": "127.0.0.1", "port": 27017 } mongodb.options.secondary_read_preference:true mongodb.db:handmade mongodb.collection:logData index.name:myindex index.type:classdata _id:_meta _type:river _index:myindex _score:0

出什么问题了？
