Big Data is the IT industry’s new buzzword. Apache’s Hadoop is used by IT giants Yahoo, Facebook & Google as a leading Big Data platform. The Big Data Hadoop industry is developing tremendously and shows no signs of deceleration. The transition between your current profession and your dream profession may be due to Big Data & Hadoop skills.
However, with continuous updates and added features and members in its ecosystem, Hadoop is a growth industry. Therefore, of course, a difficult question is how to start studying Hadoop for beginners and what to cover?
Skills required to learn Hadoop
Hadoop requires the full assistance of different programming languages. Core Java programming or advanced programming skills such as Python or even R, maybe this. You can use any of the object-oriented programming languages to write apps for Hadoop. Plus, some of Hadoop’s components support their programming languages, such as Pig supporting Pig Latin, and so on.
Whatever role you play in Big Data, knowledge of SQL is essential. Many businesses that used RDBMS are either switching to the Big Data arena or using a Big Data platform to incorporate their current infrastructure. Most of the industry-wide Hadoop implementations are focused on Linux. It is beneficial to have a previous basic working knowledge of Linux. Also, Hadoop versions 2.2 and later have native Windows support.
