From Relational to Hadoop - Migrating your data pipeline
1 April 9:30AM - 12:30PM @ Ballroom F
3 hours tutorial
This tutorial is for experienced MySQL database professionals who are interested in using Hadoop as a way to scale ETL processes. In the tutorial, we will look at an entire ETL process and for each stage demonstrate how to implement it in Hadoop. The tutorial will contain live demonstration of Hadoop ETL techniques. We will provide demo Hadoop servers in the cloud for all attendees to run the examples with prepared datasets. Attendees will need to bring their own laptops. Knowledge of Hadoop is not required. We will begin with a quick Hadoop primer where we will explain Hadoop's architecture and its core components: Map Reduce and HDFS. The rest of the tutorial will built on this understanding and show how Hadoop's unique architecture can be applied to optimize ETL processes. The tutorial will continue with a discussion of different data ingestion methods and a demonstration of Sqoop to pull data from MySQL to Hadoop. Once the data is loaded to the system we will demonstrate the use of Hive for data transformation. We'll compare HQL to more familiar SQL and the attendees will experiment with running Hive queries and using Hive UDFs. We will also demonstrate the use of Oozie to manage the ETL workflow. Attendees will leave knowing how to take the first steps in using Hadoop as part of their data processing pipeline and familiar with some of the popular tools they can use in their implementation.
