It has become a known fact that big data has been hogging the limelight in many sectors in the recent times. Such is the powerfulness of big data that 79% of executives feel that companies may lose their competitive position and might even end up in extinction if they do not embrace big data, according to a study by Accenture.

Pig Latin has a simple syntax with powerful semantics we will use to carry out two primary operations:

Developers and Programmers are still continue to explore various approaches to leverage the distributed computation benefits of MapReduce and the almost limitless storage capabilities of HDFS in intuitive manner that can be exploited by R.

Simple” often sense as “elegant” when it comes to those remarkable architectural drawings for that new Silicon Valley mansion we have planned for when the money starts rolling in after we implement Hadoop.

Mapper class is responsible for providing implementations for mapping jobs in MapReduce.

HDFS is one of the two main components of the Hadoop framework; the other is the computational paradigm known as MapReduce.

In HDFS, the Data block size needs to be large enough to warrant the resources dedicated to an individual unit of data processing On the other hand.

Hadoop has gone through some big API change in its 0.20 release, which is the basic interface in the 1.0 version .

As we already know that in Hadoop, files are composed of individual records, which are ultimately processed one-by-one by mapper tasks.

The massive data volumes that are very command in a typical Hadoop deployment make compression a necessity.

From the beginning of the Hadoop’s history, MapReduce has been the complete game changer in town when it comes to deal with data processing.

Commercially available distributions of Hadoop offer different combinations of open source components from the Apache Software Foundation and from several other places

A number of companies offer tools designed to help you get the most out of your Hadoop implementation. Here’s a sampling:

First of all, let’s just clarify about what do we meant by saying “key-value” pairs by understanding similar concepts in the Java standard API.

There are several other open source components that are typically seen in a Hadoop deployment.
