Deploying Hadoop + MongoDB Running environment

First download Mongo-hadoop Adapter

git clone https://github.com/mongodb/mongo-hadoop.git

git checkout release-1.0

Then go to the Mongo-hadoop directory and find BUILD.SBT to modify hadoop920.html ">release in Thisbuild as follows:

Hadooprelease in Thisbuild: = "0.20"

Then run./SBT package (about SBT Https://github.com/harrah/xsbt/wiki)

It is necessary to turn the & wall when running.

At the end of the run, a jar file Mongo-hadoop-core_0.20.205.0-1.0.1.jar is core/target in the directory, then the MongoDB driver package is downloaded.

wget--no-check-certificate Https://github.com/downloads/mongodb/mongo-java-driver/mongo-2.7.3.jar After downloading, you can start to develop the Mongo-hadoop program.

Run the sample: first import the data into the MongoDB, and the commands are as follows.

./SBT Load-sample-data

Then create a new project in Eclipe, such as Treasury, to copy the source and resource files from Mongo-hadoop/example/treasury_field to the new project.

As shown in the figure:

Then modify the URL of the MongoDB in the Mongo-treasury_yield.xml file and store collection

Mongo.input.uri

Mongodb://127.0.0.1/mongo_hadoop.yield_historical.in

Mongo.output.uri

Mongodb://127.0.0.1/mongo_hadoop.yield_historical.out

Then modify the Treasuryyieldxmlconfig.java as follows:

Configuration.adddefaultresource ("Resources/mongo-treasury_yield.xml");

Configuration.adddefaultresource ("Resources/mongo-defaults.xml");

The project is packaged into a jar file.

Run Hadoop jar Treasury.jar Com.mongodb.hadoop.treasury.TreasuryXMLConfig to run the Hadoop program. The results of the operation are as follows: Data in MongoDB.
