We delve into the world of Hadoop and all that it can offer. Android/iPad versions available to download too!

 

The latest issue of Java Tech Journal, the free PDF magazine that delves deeper into a topic from within the Java ecosystem, is now available to download for FREE.

Java Tech Journal covers all the hot topics for Java developers. Each issue deep dives into one topic, be it the Scala programming language or Agile development. The magazine provides an insight into emerging trends in the Java universe, and offers best practices for established technologies on a monthly basis.

This issue focuses on the technology that has had everyone talking so far in 2012 – Apache Hadoop, the revolutionary method for dealing with huge amounts of data. Essentially, Hadoop at its very core is a Java-based framework split into two parts – HDFS (the data storage system) and MapReduce (which processes it). But from that, a thriving ecosystem of open source projects has sprung up such as Pig, Hive and Zookeeper. Not to mention the hub of Hadoop-centric companies springing up like Cloudera, Hortonworks and MapR.

Apache Hadoop released their first stable version right at the back end of the year, signalling to the world that they are ready for the big data challenges that lie in wait. Several large technology vendors have also seen the worth of the burgeoning technology, with all placing their faith in it. Oracle seem keenest releasing their Big Data Appliance very recently.

In this first issue of Java Tech Journal for 2012, we go on a whistle-stop tour of the entire Hadoop universe including:

  • An exclusive interview with Hortonworks founder and also Hadoop PMC Chair Arun Murthy, about the latest stable version, Hadoop 1.0 and the entire ecosystem. 
  • Hadoop in action with deep analytics - Sujee Maniyam will show us how MapReduce can be used to measure the effectiveness of an advertising campaign whilst Isabel Drost delves into various aspects of the Hadoop ecosystem and how to apply Hadoop for your own needs. Josh Wills, Director of Data Science at Cloudera also provides an excellent look at how Hadoop can be used to analyse adverse drug events. There’s no better way of learning about Hadoop by seeing first hand what it can do. 
  • Something new with Hadoop and NoSQLMatt Ingenthron shows us how the Sqoop connector can unite the duo to perform some deep analytics. 

We hope this issue gives you a brief glimpse into what Hadoop can do, if you’re a newcomer. In any case, Hadoop is here to stay. This is the year of the elephant. Enjoy the issue!
