Big Data Challenges


Why Hadoop?


What is Hadoop?

ᗍ Hadoop is open source framework for big data. Both distributed storage and processingᗍ Hadoop is reliable and fault tolerant with no rely on hardware for these propertiesᗍ Hadoop has unique horizontal scalability


Tasks of a Hadoop Developer

The following are the tasks of a Hadoop Developer:

ᗍ Development and implementationᗍ Loading from disparate data setsᗍ Pre-processing ᗍ Designing, building, installing, configuring and supporting Hadoopᗍ Translate complex functional and technical requirements into detailed designᗍ Perform analysis on big dataᗍ Securing Dataᗍ Create scalable and high-performance web services for data trackingᗍ High-speed queryingᗍ Managing and deploying


Let us Look at the Top 5 Tasks of a Hadoop Developer with Examples


Task 1: Development and Implementation

A Hadoop developer is responsible for the actual coding/programming of Hadoop applications

One of the most important component of Hadoop is MapReduce in which you need to write Java programs – all you need is a basic Java background


Task 2: Loading from Disparate Data Sets

Disparate Data are heterogeneous data

They are neither similar nor can be easily integrated with an organizations database management system. It differs in one or more aspects of an information system

Disparate data may be characterized by these basic problems:

ᗍ Implementing a database system in an organization, there is no complete and integrated inventory of all its data

ᗍ High data redundancy all over the organization

ᗍ High variability of data formats and contents


Task 2: Loading from Disparate Data Sets – Scenario

Consider a web application where a user can send a query on getting a variety of information about various aspects such as crime statistics, weather, hotels, demographics, etc. in a particular city

Traditionally, the information must be stored in a single database with a single schema

But it would be difficult for any single enterprise to process and expensive to collect


Task 3: Perform Analysis on Big Data

A Hadoop Developer perform and analyses the big data


Task 3: Perform Analysis on Big Data – Example

Have you ever wondered how Google, Facebook or LinkedIn manages to store and utilize the huge data?Today, it is becoming a problem for all of us to manage such BIG DATA….


Task 4: Securing Data

One of the biggest concerns in our present age revolves around the security and protection of sensitive information

Network security breaches from internal and external attackers are on the rise, often taking months to be detected, and affects the organizations terribly


Task 5: Managing and Deploying

Managing the Hadoop Cluster. This is done using HBase
