I’m working on a video series for O’Reilly that aims to de-mystify Hadoop and MapReduce, explaining how mere mortals can analyze massive data sets. I’m recording the first drafts of my segments now, a...

A MapReduce overview

Towards Data Science

When I first started reading about MapReduce, nearly every tutorial intro’d with a Java or C++ prerequisite reminder. Yet there’s also the outdated (and increasingly sparse) mindset in the tech world…...

MapReduce for Idiots

Pete Warden's blog

Photo by Stuart Pilbrow I'll admit it, I was intimidated by MapReduce. I'd tried to read explanations of it, but even the wonderful Joel Spolsky left me scratching my head. So I plowed ahead trying to...

How Map Reduce Let You Deal With PetaByte Scale With Ease

Analytics Vidhya

Map Reduce is the core idea used in systems which are used in todays world to analyse and manipulate PetaByte scale datasets (Spark, Hadoop). Knowing about the core concept gives a better…

MapReduce with Python

Python in Plain English

MapReduce with Python is a programming model. It allows big volumes of data to be processed and created by dividing work into independent tasks. It further enables performing the tasks in parallel…

MapReduce for Idiots: The Musical

Pete Warden's blog

MapReduce for Idiots I've just uploaded an audio slideshow of the talk I gave at Gnip last week, covering why MapReduce really isn't scary and why you should be looking into it for your problems. I'll...

MapReduce in C from Scratch Using Threads: Map

Towards Data Science

Borrowing from functional programming, the MapReduce team realized a lot of different problems could be divided into two common operations: map, and reduce. This meant as long as you could frame your…...
