Tech Article: How to Set Up a Hadoop 2.2 Cluster From the Unified Archive.
Learn how to combine an Apache Hadoop 2.2 (YARN) cluster using Oracle Solaris Zones, the ZFS file system, and the new Unified Archive capabilities of Oracle Solaris 11.2 to set up a Hadoop cluster on a single system.
Also see how to configure manual or automatic failover, and how to use the Unified Archive to create a “cloud in a box” and deploy bare-metal system.
The article starts with a brief overview of Hadoop and follows with an example of setting up a Hadoop cluster with two NameNodes, a Resource Manager, a History Server, and three DataNodes. As a prerequisite, you should have a basic understanding of Oracle Solaris Zones and network administration.
