Mongodb 无法在HDP中的配置单元查询中使用mongo hadoop连接器

我是hadoop新手。我已经安装了hortonworks沙盒2.1。 我正在尝试使用配置单元UI执行配置单元脚本。我想访问蜂巢内的mongo收藏。为此，我使用了以下查询：

CREATE TABLE individuals
( 
  id INT,
  name STRING,
  age INT,
  city STRING,
  hobby STRING
)
STORED BY 'com.mongodb.hadoop.hive.MongoStorageHandler'
WITH SERDEPROPERTIES('mongo.columns.mapping'='{"id":"_id"}')
TBLPROPERTIES('mongo.uri'='mongodb://<hostIP>:27017/test.test');

有人能帮我告诉我我错过了什么吗

提前感谢。

您需要映射mongodb集合中的所有项目，而不仅仅是“\u id”：

创建表个人
( 
id INT，
名称字符串，
年龄智力，
城市弦，
爱好串
)
由'com.mongodb.hadoop.hive.mongostragehandler'存储
使用serdeProperty（'mongo.columns.mapping'='{“id”：“\u id”，“name”：“，“age”：”等..}'）
TBLProperty（'mongo.uri'='mongodb://:27017/test.test'）；

谢谢你。我可以创建表格。但现在，当我尝试使用select*from table_name获取数据时，它失败了，出现了-java.io.IOException:com.mongodb.MongoTimeoutException:10000毫秒后等待连接时超时。
