Dear DataKRKers, we're hosting a workshop this time. Bring your laptop to benefit most, but it's also ok to come bare-handed and watch.


Have you ever been annoyed at a new toy being broken by your 3-year old? I have. But guess what - every time I pick up some new technology I start behaving like a 3-year-old myself. I want to see what's going to happen if I press here or bend it there. Or indeed - how much the thing can be squeezed before it cracks or worse! Call it vandalism if you will, but it can be a very instructive process. By succumbing to this urge you start 'feeling' the different components of the technology. What it can do, what it's limits are. There's a term coined for this sort of technology 'feeling' - mechanical sympathy. Look it up it makes for a great reading.

Unlike the 3-year-old's toys that you need to throw away once broken, we're dealing with software here, so with tools like Docker under your belt the crash is, well, soft and easy to fix.

So let's inflict some pain on Apache Spark and see how and where it cracks.

After attending the workshop you'll be able to:
- deploy Apache Spark to run locally on your laptop using Docker
- run a simple distributed Python spark app in Jupyter Notebook
- see how it's all connected using Spark UIs
- follow the cycle: break it, feel it broken, fix it


- NOTE: it's ok if you come barehanded - you'll be able to just follow it all on screen
- have a laptop with:
- installed Docker Community Edition (
- installed git (
- run the following commands to download the necessary software for offline use
> docker pull dimajix/jupyter-spark
> git clone
