How to Become a Hadoop Architect?

Evolving as a vital link between businesses and technology, Big Data Hadoop Architects are among the professionals who are in great demand. With the progression in computer technology and massive growth in businesses, the importance of data has increased at an unprecedented level. This in turn has made the role of a Data Analyst paramount and led to the development of Big Data Hadoop architecture. Hadoop Architects are responsible for planning and designing advanced big-data systems and handling the large-scale development of Hadoop applications. Those who want to build a career as a Hadoop Architect can do so by taking up courses in Information Technology or Computer Science. 

Who is a Hadoop Architect?

Hadoop, which is written in Java, is an open-source framework from Apache which is used to store, process, and analyze high-volume data. Used for offline processing, it has wider applications as it is used by Tech giants like Facebook, Yahoo, Google, Twitter, LinkedIn, and many more. A Hadoop cluster consists of a server and an array of nodes. It offers a flexible, scalable, and reliable distributed computing big data network to process an enormous volume of data with storage capacity and local computing power by using commodity hardware.

The important components of Hadoop Architecture

• Hadoop Distributed File System (HDFS) – Patterned after the UNIX file system
• Hadoop MapReduce
• Yet Another Resource Negotiator (YARN)

Understanding Hadoop Architecture

Hadoop was originally developed by Google to support its search engine but the Apache Software Foundation has since taken the reins. Many organizations are using Apache Hadoop for storing and processing big data sets from various sources like social media, click-stream data, or log files.

Tata Consultancy Services (TCS), Intel, Amazon, Facebook, and eBay are some of the companies that use Hadoop for various tasks like fraud detection, customer segmentation, and analysis of click-stream data. Therefore if you wish to make your way into the Big Data field then you cannot afford to ignore Hadoop.

Choosing Education

A highly demanding field, Hadoop Architecture has widespread applications. If you are keen to know about the educational requirements to become a Hadoop Architect then you must know that by pursuing courses in Data Analytics and Data Science you can start a career in the field. The courses can be studied as sub-field of Computer Science or as separate specialization at the master’s level. Moreover, the courses pursued at the postgraduate level span over 1-2 years.
