I am extremely happy to say that my proposal was accepted for Hadoop Summit 2014 in Amsterdam ;) The title of my presentation is Hadoop operations powered by … Hadoop and I will talk about various metrics, logs and files that Hadoop generates and how to analyze them … using Hadoop (and open-source tools and simple scripts) to learn more about Hadoop and avoid guesstimates!

Last month, I had to pleasure to give the Ignite presentation about “Hadoop Playlist”, at NYC Strata 2013. Although, I am not the greatest speaker, I hope you will enjoy my presentation!

I am very happy to present the slides from my presentation at Strata + Hadoop World 2013.
The presentation is titled ” Hadoop adventures at Spotify” and I am simply talking about five real-world Hadoop issues that either broke our cluster at Spotify or made it very unstable. Each story comes from our JIRA dashboard and is based on facts! ;) To make it even more engaging, I am exposing real graphs, numbers, even our emails and conversations. For each story, I am sharing the mistakes that we made and I am describing the lessons that we learned.
This includes also the mistake that I made and I do not like to talk about, but today I will share it as well ;)
