Overview – This course is designed for developers who want to create custom YARN applications for Apache Hadoop. It will include: the YARN architecture, YARN development steps, writing a YARN client and ApplicationMaster, and launching Containers. The course uses Eclipse and Gradle connected remotely to a 7-node HDP cluster running in a virtual machine.

Target Audience – Java software engineers who need to develop YARN applications on Hadoop by writing YARN clients and ApplicationMasters


Prerequisites – Students should be experienced Java developers who have attended HDP Developer: Java OR HDP Developer: Pig and Hive OR are experienced with Hadoop and MapReduce development.

Course ObjectivesAt the completion of the course students will be able to:

  • Describe the YARN architecture
  • Describe the YARN application lifecycle
  • Write a YARN client application
  • Run a YARN application on a Hadoop cluster
  • Monitor the status of a running YARN application
  • View the aggregated logs of a YARN application
  • Configure a ContainerLaunchContext
  • Use a LocalResource to share application files across a cluster
  • Write a YARN ApplicationMaster
  • Describe the differences between synchronous and asynchronous ApplicationMasters
