ElasticSearch批量更新中的NullPointerException

Question

我試圖在使用批量更新的ES索引中爲文檔添加建議字段，但我不斷收到NullPointerException作爲響應。這裏是什麼，我試圖做一個例子：使用ES 1.1.1

命令使用curl

：

curl -s -XPOST "http://www.example.com/test_index/entity/_bulk" --data-binary @tmp 

tmp文件裏面：

{"update": {"_type": "entity", "_id": "fbf804af945d13d9b7c076948bc1bd19", "_index": "test_index"}} 
{"lang": "js", "params": {"input_name": {"input": ["calcium"]}}, "routing": "434750445cdc9cea954399185e4b3da8", "script": "ctx._source.suggest = input_name"} 

我得到這個迴應：

{"error":"NullPointerException[null]","status":500} 

但是，如果我做一個正常的更新，它工作正常：

curl -s -XPOST "http://www.example.com/test_index/entity/fbf804af945d13d9b7c076948bc1bd19/_update?routing=434750445cdc9cea954399185e4b3da8" --data-binary @tmp 

{ 
    "script": "ctx._source.suggest = input_name", 
    "params": { 
     "input_name": { 
      "input": [ 
      "calcium" 
      ] 
     } 
    } 
} 

這裏是爲實體的映射是這樣的：

entity: { 
    _parent: { 
     type: post 
    } 
    _routing: { 
     required: true 
    } 
    properties: { 
     suggest: { 
      type: completion 
      analyzer: simple 
      payloads: false 
      preserve_separators: true 
      preserve_position_increments: true 
      max_input_length: 50 
     } 
     type: { 
      type: string 
      index: not_analyzed 
      store: true 
     } 
     value: { 
      type: string 
      index: not_analyzed 
      store: true 
     } 
    } 
}

索引中的映射，可以設置路由到必需的，這樣在cmd部分您需要指定路由參數：

{"update": {"_type": "entity", "_id": "fbf804af945d13d9b7c076948bc1bd19", "_index": "test_index", **** --> "routing: "fbf804af945d13d9b7c076948bc1bd19" }}
