我正在尝试使用wiki站点上提供的驱动程序（jars）从配置单元数据库连接到mongodb中的集合。以下是我所做的步骤：-
我在mongodb的“moe”数据库下创建了一个名为“diamond”的集合，它有20个文档：
我想通过hadoopmongodb驱动程序从hive连接，并通过hive查看这些文档。
我已经将mongodb和hive安装在同一台服务器上并进行了配置。然而，我没有看到任何变量称为Hive，我想知道它在哪里。

So I installed 3 divers on the server: -
mongo-hadoop-core-1.5.2.jar;
mongo-hadoop-hive-1.5.2.jar;
mongo-java-driver-3.0.0.jar;

现在，我连接到hive，然后通过以下命令将这两个jar添加到我的类路径：-（它们被成功添加）

add jar /hadoopgdc/hadoop-2.6.0/share/hadoop/common/lib/mongo-hadoop-hive-1.5.2.jar;
add jar /hadoopgdc/hadoop-2.6.0/share/hadoop/common/lib/mongo-hadoop-core-1.5.2.jar;
add jar /hadoopgdc/hadoop-2.6.0/share/hadoop/common/lib/mongo-java-driver-3.0.0.jar;

现在我在配置单元中创建一个表：-

CREATE TABLE Diamond
(
carat    DOUBLE,
cut      STRING,
color    STRING,
clarity  STRING,
depth    DOUBLE,
table    DOUBLE,
price    DOUBLE,
xcord    DOUBLE,
ycord    DOUBLE,
zcord    DOUBLE
)
STORED BY 'com.mongodb.hadoop.hive.MongoStorageHandler'
WITH SERDEPROPERTIES('mongo.columns.mapping'='{"carat":"carat","cut":"cut",                 
"color":"color", "clarity":"clarity", "depth":"depth", "table":"table", 
"price":"price", "xcord":"x", "ycord":"y", "zcord":"z"}')
TBLPROPERTIES('mongo.uri'='mongodb://localhost:27017/Moe.Diamond');

However when I execute the above command in Hive I get the error below: -

我尝试了以下方法：-将jar放在每个可能的目录中，但没有效果-应该缺少的类几乎存在于jar文件中。-哦，是的，mongostragehandler类就在jar里。
我已经受够了！！如果有人能告诉我该怎么做来减轻我的焦虑，那就太好了。
再次感谢。马里奥
