Hadoop Big data Online Training

Hadoop and  Big Data are fast becoming an emerging trend for effectively storing and managing the humongous data that businesses generate by organizing the storage across a distributed server architecture and creating a retrieval process that greatly optimizes the actual process for increased efficiency. BigData is the name given to enormous amount of unstructured data which can be in different formats and file types such as media, text, logs etc as opposed to convention RDBMS (Relational Database Management System) which consists of defined field types.  Hadoop is a platform for managing such big data and create an efficient, secure, robust and optimized storage and retrieval mechanism that can handle such unstructured data. It’s an open-source initiative started by Doug Cutting in 2005 and has been a product of an extensive development process that has been inspired from and then promoted by some of the world’s biggest  data generators-the search engines. It was developed as no existing solution then could efficiently manage the future projection of the amount of data being stored and indexed.

Features :

Hadoop has been designed as an open-source software framework for BigData storage and processing and is implemented using a series of existing parallely aligned servers. It solves the common data storage challenge of hardware failure by organizing the data into portions stored in multiple locations (Done by HDFS –Hadoop Distributed File System) Most importantly, it’s suited for analyzing unstructured data and can easily uncover trends and analytics from raw data which was previously computationally expensive.

It is built on the programmable model of parallel processing and organizes the constituent servers so that they work in tandem on individual bits of processing requirements such as queries and then the result set is put together from all of them (Map Reduce is the programmable part of the framework that controls such assignment)

It’s robust, fault tolerant, highly optimizes processing of data and is very cost-effective for big data storage and processing.
