Chapter 7. Optimizing the Performance of a Cascading Application

Optimizing performance by tuning a Cascading application is essential in order to ensure speedy and reliable execution. This chapter will provide in-depth information on how to efficiently optimize a Cascading application and configure the underlying framework (Hadoop) for maximum performance.

You will learn what to look for when determining performance characteristics. We will be:

  • Examining practices for improving the performance of a Cascading application

  • Discussing how to make performance changes to the underlying Hadoop system when Cascading is running on a specific platform

  • Showing how to effectively use checkpoints to help with processing time when failures occur

  • Overviewing several open source and commercial tools that can help us to diagnose performance of a Cascading application
