blog-spark-streaming-log-aggregation's Introduction

Simple example consuming an adserver logs stream from Kafka.

More information on our blog: http://chimpler.wordpress.com/2014/07/01/implementing-a-real-time-data-pipeline-with-spark-streaming/

In order to run our example, we need to install the followings:

Building the examples:

$ sbt pack

Create a topic “adnetwork-topic”:

$ kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic adnetwork-topic

Start Zookeeper:

$ zookeeper-server-start.sh config/zookeeper.properties

Start Kafka:

$ kafka-server-start.sh config/kafka-server1.properties

Run MongoDB: $ sudo mongod

On one window, run the aggregator:

$ target/pack/bin/aggregator

On the other one, run the adserver log random generator:

$ target/pack/bin/generator

You can also see the messages that are sent using the Kafka console consumer:

$ kafka-console-consumer.sh --topic adnetwork-topic --zookeeper localhost:2181

After a few seconds, you should see the results in MongoDB:

$ mongoexport -d adlogdb -c impsPerPubGeo --csv -f date,publisher,geo,imps,uniques,avgBids
connected to: 127.0.0.1
 
date,publisher,geo,imps,uniques,avgBids
