I am very happy to share my slides from the presentation about Apache Hadoop YARN that I gave at the 9th meeting of Warsaw Hadoop User Group 2 days ago.

The slides cover motivation for YARN, description of all YARN daemons, some interesting features and the most interesting configuration parameters and many, many pictures. Hope you will find it useful (please refresh this page if slides do not appear).

I am happy to say the first Hadoop User Group has already been opened in Stockholm, Sweden. We are really excited to see that Hadoop community in Stockholm is so thriving. Actually, the meetup generated pretty big interest and in consequence almost 150 people attended the event!

The meetup was organized in the Cafeteria at Spotify, and two talks were delivered.

Football zero, Apache Pig hero – the essence from hundreds of posts from Apache Pig user mailing list

I am big fan of football and I really like reading football news. Last week however, I definitely overdid reading it (because Poland played against England in the World Cup 2014 qualifying match). Hopefully, I did realize that it is not the best way to waste my time and today I decided that my next 7 days will be different. Instead, I will read posts from Apache Pig user mailing lists!

The idea is just to read post from the mailing list anytime I feel like reading about football. It means Football zero, Apache Pig hero for me this week ;)
