Hadoop becomes imperative to process a large and complex set of data. However, often the issue of architecture scalability pose unnecessary roadblock in this process. OpenStack – an open-source software instills the required operational flexibility to scale-out architecture for Hadoop. This session will throw light on how we helped a client install Hadoop on VMs using OpenStack. We will discuss in-depth the challenges of manual operations and how we overcame them with Sahara. The audience will also learn why we virtualized hardware on the computing nodes of OpenStack and deployed VMs.
