Hadoop Training in Hyderabad

What is Hadoop?

Hadoop in a nutshell is a framework which provides a shared storage and analysis system. The storage is provided my HDFS and analysis by Mapreduce. There are other parts in hadoop but these are the main ones which catch our eye. It allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage.

Why I need Apache Hadoop?

Hadoop brings the ability to cheaply process large amounts of data, regardless of its structure. By large, we mean from 10-100 gigabytes and above. Existing enterprise data warehouses and relational databases excel at processing structured data and can store massive amounts of data, though at a cost: This requirement for structure restricts the kinds of data that can be processed, and it imposes an inertia that makes data warehouses unsuited for agile exploration of massive heterogenous data. The amount of effort required to warehouse data often means that valuable data sources in organizations are never mind. This is where Hadoop can make a big difference.

Who can learn Apache Hadoop?

Hadoop is a framework for Java Development. This framework helps you build the applications implementing the logic of map and reduce much easier. Anyone with prior understanding and acquaintance with the concepts of core java is ready to start.

Job Prospects in Hadoop

New job opportunities are emerging for IT professionals in the field of "big data," the term used to describe how corporations gather vast amounts of real-time data about their customers and analyze that data to drive decision making and increase profitability.

Pre-requisites:

1. Coding experience using concepts of Core Java

2. Basic understanding of Linux Commands.
