Hadoop Cluster with Oracle Solaris Hands on Lab at Oracle Open WORLD 2013

If you want to learn how-to build a Hadoop cluster using Solaris 11 technologies please join me at the following Oracle Open WORLD 2013 lab.
How to Set Up a Hadoop Cluster with Oracle Solaris [HOL10182]



In this Hands-on-Lab we will preset and demonstrate using exercises how to set up a Hadoop cluster Using Oracle Solaris 11 technologies like: Zones, ZFS, DTrace  and Network Virtualization.
Key topics include the Hadoop Distributed File System and MapReduce.
We will also cover the Hadoop installation process and the cluster building blocks: NameNode, a secondary NameNode, and DataNodes.
In addition how we can combine the Oracle Solaris 11 technologies for better scalability and data security.
During the lab users will learn how to load data into the Hadoop cluster and run Map-Reduce job.
This hands-on training lab is for system administrators and others responsible for managing Apache Hadoop clusters in production or development environments.

This Lab will cover the following topics:

    1. How to install Hadoop

    2. Edit the Hadoop configuration files

    3. Configure the Network Time Protocol

    4. Create the Virtual Network Interfaces

    5. Create the NameNode and the Secondary NameNode Zones

    6. Configure the NameNode

    7. Set Up SSH between the Hadoop cluster member

    8. Format the HDFS File System

    9. Start the Hadoop Cluster

   10. Run a MapReduce Job

   11. How to secure data at rest using ZFS encryption

   12. Performance monitoring using Solaris DTrace

How to Set Up a MongoDB NoSQL Cluster Using Oracle Solaris Zones

This article starts with a brief overview of MongoDB and follows with an example of setting up a MongoDB three nodes cluster using Oracle Solaris Zones.
The following are benefits of using Oracle Solaris for a MongoDB cluster:

• You can add new MongoDB hosts to the cluster in minutes instead of hours using the zone cloning feature. Using Oracle Solaris Zones, you can easily scale out your MongoDB cluster.
• In case there is a user error or software error, the Service Management Facility ensures the high availability of each cluster member and ensures that MongoDB replication failover will occur only as a last resort.
• You can discover performance issues in minutes versus days by using DTrace, which provides increased operating system observability. DTrace provides a holistic performance overview of the operating system and allows deep performance analysis through cooperation with the built-in MongoDB tools.
ZFS built-in compression provides optimized disk I/O utilization for better I/O performance.
In the example presented in this article, all the MongoDB cluster building blocks will be installed using the Oracle Solaris Zones, Service Management Facility, ZFS, and network virtualization technologies.

Figure 1 shows the architecture:
