HDFS vs. HBase : All you need to know

It has created the need for a more organized file system for storage and processing of data, when it is observed a sudden increase in the volume of data from the order of gigabytes to zettabytes.


Pig Script Interfaces and Mode of Running in Hadoop

All scripts are run on a single machine without requiring Hadoop MapReduce and HDFS. This can be useful for developing and testing Pig logic.

Introduction to Ooize in Hadoop

Moving data and running different kinds of applications in Hadoop is great stuff, but it’s only half the battle.

Statistical Analysis in Hadoop

Big data is all about applying analytics to more data, for more people.

Pig Data Types in Hadoop

We have already seen the Pig architecture and Pig Latin Application flow. We also learn the Pig Design principle in the previous post.

Pig Design Principles in Hadoop

Pig Latin is the programing platform which provides a language for Pig programs. Pig helps to convert the Pig Latin script into MapReduce tasks that can be run within Hadoop cluster.

Introduction to Pig in Hadoop

Java MapReduce programs and the Hadoop Distributed File System (HDFS) provide us with a powerful distributed computing framework, but they come with one major drawback

Hadoop File System Commands: ls Command Output Analysis

In my previous post, I have explained various Hadoop file system commands, in which I also explained about the “ls command”.

HDFS Architecture in Hadoop

The core concept of HDFS is that it can be made up of dozens, hundreds, or even thousands of individual computers, where the system’s files are stored in directly attached disk drives.

Three modes of Hadoop Cluster Architecture

Hadoop is primarily structured and designed to be deployed on a massive cluster of networked systems or nodes,

Why we need Map-Reduce in Hadoop?

After we have stored piles and piles of data in HDFS (a distributed storage system spread over an expandable cluster of individual slave nodes),

Various Data compression codecs in Hadoop

Here we enlist and identify some common codecs that are supported by the Hadoop framework.

Hadoop Toolbox

Besides, the major contribution of Amazon EMR services and its other related tools, many other companies also provide certain useful Hadoop Tools enlisted as following:

Concept of Map Reduce in Hadoop

Though MapReduce as a technology is relatively new, it builds upon much of the fundamental work from both mathematics and computer science,

Hadoop Distributions: EMC, HotonWork and MapR

Besides Cloudera, there are few other popular Hadoop distribution which are well implemented for commercial and development purposes.

Hadoop Distributed processing with MapReduce

MapReduce comprises the sequential processing of operations on distributed volumes of data sets.
