In this tutorial we will be setting up Apache Spark on a cluster of Tizen development devices , which is very easy to do. Make sure you have root SSH access to each of the devices (Wifi network in configured, SSH server is up and running and you have Internet access).
The cluster will be composed of one RD-PQ device acting as the master node and two RD-210 devices acting as slave nodes; the RD-PQ is powered by a quad core ARMv7 CPU while the RD-210 is a dual core device. Both types have 1Gb of RAM that should be more than ok for testing and understanding how a cluster works.
In this small article you will be able to find out information about the two development devices created by Samsung for the Tizen OS. Keep in mind that RD-PQ is also called M0 internally at Samsung.
The Samsung RD-PQ developer device running Tizen 2.3.1 can be a cool development server/machine, and you can add git repository hosting and administration with just a few easy steps.
First of all, let’s compile and install git .
This article assumes you have internet access on your Tizen device, an OpenSSH daemon running and you can connect to it via a SSH client. If you don’t, please read the other articles in the series. If you do, read below on how to install various development tools on your RD-PQ device running Tizen 2.3.1 (and possibly, 2.3, though not tested).
In the previous articles I showed you how to install Tizen 2.3.1 on a Samsung RD-PQ developer device, enable WiFi connection, connect to a WiFi network and install SSH server so you can remotely connect to your phone via your favorite SSH client. In this article I’m going to show you how to customise your Tizen OS and rid it of unnecessary packages, runtime systemd scripts, Xorg UI and many more.
