Big Data and Hadoop
In a world where data is fueling the growth of organizations, it wont be wrong to assume that companies ingest raw data in large volumes from numerous sources. But, how can they identify the data which is both useful and insightful? This is where Big Data comes to play. Hadoop is an open source framework that is used to process Big Data. The average salary of a Big Data analyst in the US is around $61,000.

So this Tutorial is intended towards those individuals who are awed by the sheer might of Big Data Read More
The Data Challenges at Scale and The Scope Of Hadoop
The challenges of Big Data
Big Data by its very nature is hugely challenging to work with. But the rewards of making sense of Big Data is hugely rewarding too. All Big Data can be categorized into: Structured –that which can be stored in rows and columns like relational data sets Unstructured – data that cannot be stored in rows Read More
Comparison To Existing Database Technologies
Apache Hadoop vs other Database technologies
Most database management systems are not up to scratch for operating at such lofty levels of Big data exigencies either due to the sheer technical inefficiency or the insurmountable financial challenges posed. When the type of data is totally unstructured, the volume of data is humongous, the results needed are at breakneck speeds, then Read More
The Hadoop Module & High-level Architecture
The Apache Hadoop Module:
Hadoop Common: this includes the common utilities that support the other Hadoop modules HDFS: the Hadoop Distributed File System provides unrestricted, high-speed access to the application data. Hadoop YARN: this technology accomplishes scheduling of job and efficient management of the cluster resource. MapReduce: highly efficient methodology for parallel processing of huge volumes of data. Then there are Read More
Introduction To Hadoop Distributed File System
HDFS and its Architecture
Hadoop stores petabytes of data using the HDFS technology. Using HDFS it is possible to connect commodity hardware or personal computers, also known as nodes in Hadoop parlance. These nodes are connected over a cluster on which the data files are stored in a distributed manner. Using the power of HDFS the whole cluster and the Read More
Hadoop Multi Node Clusters
Setting up Hadoop Multi-Node Cluster
Installing Java Syntax of java version command $ java -version Following output is presented. java version "1.7.0_71" Java(TM) SE Runtime Environment (build 1.7.0_71-b13) Java HotSpot(TM) Client VM (build 25.0-b02, mixed mode) Creating User Account System user account on both master and slave systems should be created to use the Hadoop installation. # useradd hadoop Read More
HDFS Installation and Shell Commands
Setting up of the Hadoop cluster: Here you will learn how to successfully install Hadoop and configure the clusters which could range from just a couple of nodes to even tens of thousands over huge clusters. So for that, first you need to install Hadoop on a single machine. The requirement for that is you need to install Java if Read More
Hadoop MapReduce – Key Features & Highlights
The highlights of Hadoop MapReduce
MapReduce is the framework that is used for processing large amounts of data on commodity hardware on a cluster ecosystem. The MapReduce is a powerful method of processing data when there are very huge amounts of node connected to the cluster. The two important tasks of the MapReduce algorithm are, as the name suggests Read More
Hadoop YARN Technology
What is Hadoop Yarn?
The Apache Hadoop YARN stands for Yet Another Resource Negotiator. It is a very efficient technology to manage the Hadoop cluster. YARN is a part of Hadoop 2 version under the aegis of the Apache Software Foundation. YARN is a completely new way of processing data and is now rightly at the centre of The Hadoop Read More
Introduction to Pig, Sqoop, and Hive
Apache Pig The Apache Pig is a platform for managing large sets of data which consists of high-level programming to analyze the data. Pig also consists of the infrastructure to evaluate the programs. The advantages of Pig programming is that it can easily handle parallel processes for managing very large amounts of data. The programming on this platform is basically Read More
