The Hadoop MapReduce API

Learn how to get started writing programs against Hadoop’s API.

Introduction to MapReduce Algorithms

Writing programs for MapReduce requires analyzing problems in a new way. This lecture shows how some
common functions can be expressed as part of a MapReduce pipeline.

Debugging MapReduce programs

Debugging in the distributed environment is challenging. This lecture will expose you to best practices for program
design to mitigate debugging challenges, as well as local testing tools and techniques for debugging at scale.

Optimizing MapReduce Programs

We’ll use the Cloudera Training VM to work through an example where you write a MapReduce program and
improve its performance using techniques explored earlier.

NOTE: Attendees should download the Cloudera Training vm from VMWare Player (windows, linux) or VMWare Fusion (OS X) will be required in order to use it.

Two most useful explanations: 1) MapRed algorithms 2) Debugging MapRed jobs.

Great presentation.

I really enjoyed the explanation of the different map reduce algorithms (ie using map/reduce for joins).
