Various Limulus Benchmarks

Hadoop

Presentd a tutorial on  http://hadoop.apache.org/ Hadoop recently and used my original Limulus to demonstrated a four node Hadoop cluster. Some of the hardware is actually quite old. The nodes have a single dual core E6550, with 4 GB RAM, with 64MB SSD. The head node was a quad-core SandyBridge? (i5-2400S) with 4 GB RAM, 64MB SSD and .5 TB of RAID. Connections were using the crappy consumer based Realtek GigE Ethernet controllers on the nodes. Overalll it worked well. I plan on making a Hadoop VNFS so sthat it is poosibel to boot the nodes into Hadoop. Usded the  http://hortonworks.com/products Hortopnworks HDP for the Hadoop install /hortonworksdataplatform/
