How to Become a Successful Big Data Analyst Or Hadoop Developer

A big data Analyst Or Hadoop developer, therefore, is a software development professional who understands the challenges of big data and can leverage data systems and architecture such as Hadoop, to solve these challenges and make the system efficient. Data Analytics deals with the mechanical processes or algorithmic applications in developing insights from Big data.

Almost all businesses use Data Analytics to improve decision making and verify or disprove prevailing models and approaches. Data Analytics centers on inference, and concentrates principally on the interpretation that mainly depends on the analyst’s knowledge.

HDFS (Hadoop Distributed File System) breaks down large files into small blocks of a specified size (default size per block is 128mb) and distributes them across different nodes.

A considerable confusion prevails with job seekers regarding data science, big data and data analytics for preferring a career role. Experts in data engineering, data science, data analytics, data mining and many related fields in data science often work side by side with respective individual functions, but mistakenly many people interchange functional roles in these fields.

Why should become a big data Hadoop developer

hadoop developer job

Opportunities in Hadoop are rife, and the jobs are rewarding. As seen in the example above from indeed.com, a professional Hadoop Developer can expect an average salary of $100,000 per annum.

Since its adoption, Hadoop has acquired a reputation for being scalable, making it a reliable platform for storing and processing data. Not only does adopting Hadoop make dealing with big data cost -effective, but its ease of integration with analytics software like Spark makes it an ideal tool for handling a large variety of workloads. As such, Hadoop is invaluable to enterprises in verticals such as insurance, banking, manufacturing, telecom, and online retail, that generate and use big data.

The health sector, for instance, experiences a lot of information flow from Electronic Medical Records, wearables, and medical equipment, among others. Hadoop allows such institutions to store, map and process all this data and leverage it in decisions involving cure and treatment, all at a manageable cost. This, in turn, has created high demand for Hadoop developers.

What are the difference between a Big Data Developer and a Data Analyst

Data Analysts generally operate under any business stream, such as operations, strategy, product, growth, sales, marketing, etc. Data Analysts link the data platform and the business stream. They use the shared data platform and help solve business issues managing data from the data platform. They need to manage a great harmony between business and technical skills to be successful in this role.

Data Developer also known as Data Scientist, Data Engineer or Software Engineer generally operates under the Engineering wing. They set up the data programs that provide data to a data platform. They run programs like Hadoop, Spark, Custom Code, ETL tools, etc. to develop data pipelines for building and managing the data program. And to succeed in this task you need to be a strong technical chopper.
