A real Hadoop cluster using tiny single board computers (SBC for short). I bought one of these boards ( called a cubietruck) and a tiny 7” monitor. I Will install Linux and Hadoop and post it soon. A christmas present to myself.
The boards are designed by a small company in China called CubieBoard and they are much more powerful than the Raspberry Pi – 2GB RAM, 1GB NIC, SATA interface.
