I recently started playing with Hadoop recently, as reflected in my recent posts. In the process, I spent a significant amount of time setting up a Hadoop cluster made of three physical servers I have screaming in my bathroom. The process took a lot of trial and error and reaching out for help in Hadoop’s… Continue reading Hadoop 2.8.2 Cluster Configuration

Handwritten Digit Recognition with TensorFlow
I recently started playing with neural nets via TensorFlow. It’s a big departure to my reinforcement learning background. But I must say, the learning is usually the other way around for most people. That is, they first learn neural nets, then reinforcement learning. That being said, many concepts overlap. One of the many things that… Continue reading Handwritten Digit Recognition with TensorFlow
Automate Hadoop Cluster with Systemd
If you have a server that is part of the Hadoop cluster, then you probably want your Hadoop daemons to run at startup. If you have done some Linux system administration, then you have probably encounter systemctl command here and there. This command is part of the Systemd, used for bootstrapping and managing system processes.… Continue reading Automate Hadoop Cluster with Systemd

I recently started playing with Hadoop to learn some data analysis. To make it more fun, I decided to fiddle with F1 datasets, specifically the Constructor And Overall Race Results. In this post, I’ll describe the three main process involved in this task. The preparation of data, followed by the two map reduce task, mapping… Continue reading Hadoop and F1: Constructor And Overall Race Results
