Hands-on Hadoop for Developers—Understanding Map/Reduce Has code image
Lynn Langit
In this class, you’ll get hands-on experience working with a leading implementation of Hadoop: Cloudera’s CDH4 release. We’ll work with their the company’s virtual machine and concentrate on learning how to get business value from a Hadoop cluster of data by writing increasingly more complex queries. These queries are known as Map/Reduce jobs, and we will write them in Java. Even if you aren’t a Java pro, you can still get value from this class, as we will also work with higher-level languages, such as Hive’s HQL and Pig. You’ll finish this class understanding when and how to get value from a Hadoop cluster.

Prerequisite knowledge: database development using T-SQL; Java or C# helpful, but not required
