In this blog post I will talk about how to deploy a cluster, the methods I tried and my solution to resolving the prerequisites problem.

I’m fairly new to the big data field. Learning about Hadoop, I kept hearing the term “clusters”, deploying a cluster, and installing some services on namenode, some on datanode and so on. I also heard about Cloudera manager which helps me to deploy services on my cluster, so I set up a VM and followed several tutorials including the Cloudera documentation to install cloudera manager. However, every time I reached the “cluster installation” step my installation failed. I later found out that there are several prerequisites for a Cloudera Manager Installation, which was the reason for the failure to install.

The blog discussed an interesting and fun tool from Percona, tpcc-mysql. I was interested in testing the tool so I decided to play around with it in an AWS EC2 server.

In this post I will expand on the Percona blog post, since the tool lacks documentation, as well as explain how I used it to create a MySQL Benchmark in AWS.
