我是hadoop新手，需要将hadoop数据存储到mongodb中。这里我使用pig将hadoop中的数据存储到mongodb中。
我下载并注册了以下驱动程序，在给定命令的帮助下，在pig grunt shell中实现了这一点，

REGISTER /home/miracle/Downloads/mongo-hadoop-pig-2.0.2.jar
REGISTER /home/miracle/Downloads/mongo-java-driver-3.4.2.jar
REGISTER /home/miracle/Downloads/mongo-hadoop-core-2.0.2.jar

在此之后，我使用以下命令成功地从mongodb获取了数据。

raw = LOAD 'mongodb://localhost:27017/pavan.pavan.in' USING com.mongodb.hadoop.pig.MongoLoader;

然后我尝试了下面的命令将数据从pig bag插入到mongodb并获得成功。

STORE student INTO 'mongodb://localhost:27017/pavan.persons_info' USING com.mongodb.hadoop.pig.MongoInsertStorage('','');

然后我使用下面的命令尝试mongo更新。

STORE student INTO 'mongodb://localhost:27017/pavan.persons_info1' USING com.mongodb.hadoop.pig.MongoUpdateStorage(' ','{first:"\$firstname", last:"\$lastname", phone:"\$phone", city:"\$city"}','firstname: chararray,lastname: chararray,phone: chararray,city: chararray');

但是我在执行上面的命令时得到了下面的错误。
