Storing HDFS data into MongoDB using Pig

Question

I am new to Hadoop and having a requirement to store the Hadoop data into MongoDB. Here I am using Pig to store the data in Hadoop into MongoDB.

I downloaded and registered the following drivers to do this in Pig Grunt shell with the help of given command,

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

After this I successfully got the data from MongoDB using the following command.

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

Then I tried the following command to insert the data from pig bag to MongoDB and got succeeded.

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

Then I am trying the Mongo Update using the below command.

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');

But I am getting the below error while performing the above command.

I don't know What to do next please give me any suggestions on this.

Answer 1

I do not use Mongo , but from HBase experience and From the error it looks like few fields are not flatten 'ed enough for it to fit the column family. And also few of columns you are trying to STORE don't exist. See to DUMP the data instead of STORE and check if it is matching the STORE structure you have applied.
