HADOOP

What Is Hadoop?

But first, the fundamentals. According to the developer’s website, “The Apache Hadoop software library is a framework that allows for the distributed processing of huge 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.”

It’s an open-source collection of software utilities designed to work across a network of computers to solve problems that are associated with enormous quantities of data and computation. In other words, it’s a perfect tool for handling the glut of information stemming from Big Data and creating workable strategies and solutions based on that data.

What Does a Hadoop Developer Do?

A Hadoop Developer takes care of the coding and programming of Hadoop applications, in the context of Big Data. The position is similar to that of a Software Developer. Other occupations that are commonly associated with Hadoop Developer are Big Data Developer, Big Data Engineer, Hadoop Architect, Hadoop Engineer, Hadoop Lead Developer.

What Skills Does a Good Hadoop Developer Need?

A good Hadoop Developer has a particular set of skills at their disposal, though businesses and organizations may place greater or lesser emphasis on any of the below-mentioned skills. Here is a list of skills that Hadoop Developers should know. But you don’t have to be a master in EVERY single one of them!

• Mandatory Knowledge of Hadoop and its appropriate components (e.g., HBase, Pig, Hive, Sqoop, Flume, Oozie, etc.)
• A good understanding of back-end programming, with an emphasis on Java, JS, Node.js, and OOAD
• A talent for writing code that is high-performing, reliable, and maintainable
• The ability to write MapReduce jobs and Pig Latin scripts
• Exhibit strong working knowledge of SQL, database structures, theories, principles, and practices.
• Should have working experience in HiveQL.
• Possess excellent analytical and problem-solving skills, especially in the context of the Big Data domain.
• Have a useful aptitude in the concepts of multi-threading and concurrency.

What Are the Responsibilities of a Hadoop Developer?

Now that we know what kind of skills it takes to be a Hadoop Developer, what exactly do they do? A Hadoop Developer will be expected to:

• Take responsibility for the design, development, architecture, and documentation of all Hadoop applications
• Take charge of installing, configuring, and supporting Hadoop
• Manage Hadoop jobs by using a scheduler
• Write MapReduce coding for Hadoop clusters as well help to build new Hadoop clusters
• Convert complex techniques and functional requirements into the detailed designs
• Design web applications for querying data and swift data tracking, all to be conducted at higher speeds
• Propose the best practices and standards for the organization, then handover to the operations
• Perform software prototype testing and oversee the subsequent transfer to the operational team
• Pre-process data by using Pig and Hive
• Maintain company data security and privacy of Hadoop clusters
• Manage and deploy HBase
• Perform large data stores analyses and derive insights from them.
