Entry-level Hadoop Developers’ job responsibilities and skills are to code and program for Big Data Hadoop applications. The job role is much similar to that of a Software Developer, except the fact that the domain of a Hadoop Developer is Big Data. It is not merely a framework, but a widespread ecosystem with a bunch of technologies. Therefore, the opportunities are in abundance, and seeking a career in it will make you a sought-after candidate in today’s data-driven market.
Further in this blog, you will get an overview of the major Hadoop Developer job responsibilities and skills. But before that, let us try getting a basic understanding of Hadoop.
What is Hadoop? Let’s Understand How It Works!
Hadoop is a simple framework with a distributed environment wherein you can store Big Data and process it simultaneously. to the creation of many Hadoop Developer job opportunities. You will learn about various Hadoop Developer job responsibilities and skills later in this blog, but let us first understand how Hadoop works.
Hadoop has two major components, Hadoop Distributed File System (HDFS) and YARN, which stands for Yet Another Resource Negotiator. HDFS allows you to store multiple formats of data across a cluster, while YARN allows you to process the data stored across HDFS in parallel.
Do you know how YARN got its name? Its full name actually became self-deprecating humor on its developers’ part. This is why it is generally referred to by its acronym.
HDFS seems like a single unit that stores Big Data while, in reality, it uses multiple distributed nodes to store the data. HDFS follows the master-slave algorithm wherein the master is NameNode and DataNodes act as the slaves.
The NameNode contains the metadata of the information stored in DataNodes, while the actual data is in DataNodes.
YARN, on the other hand, processes all activities by allocating the resources before scheduling tasks. It consists of two components, namely, ResourceManager and NodeManager. Even YARN follows the same master-slave algorithm as HDFS. Here, the ResourceManager is the master node. After getting the processing requests, it passes bits of these requests to NodeManagers, who would later process the same. The NodeManagers are responsible for carrying out the tasks on the DataNodes of HDFS.
