Technology has changed its landscape. Everything you may hear today is revolving around some big terms like big data, cloud, AI, data science, etc. To put it in another way IT professionals are following the trajectory of these booming technologies.<\/p>\n
Big Data<\/a> is something that has taken a high momentum in last two years. And when we talk about big data, Hadoop is the ultimate term that comes to mind. No other big data processing tool has gained such market popularity than this open source tool from Apache.<\/p>\n However, Hadoop is a growing field with continuous upgradation and added features as well as members in its ecosystem. Hence, it is, of course, a challenging question how to start learning Hadoop for beginners and what to cover?<\/p>\n In this blog, we will try to familiarise you with a roadmap of learning Hadoop as a beginner.

So, basic working knowledge of Linux like commands, the editor works like wonder and makes your life easier during Hadoop installation and file management.<\/p>\n However, if you are a novice on it, you can grab an Ubuntu image and can learn the features by installing it in a virtual box.<\/p>\n Hadoop is not restricted to any particular job role and handles different languages depending on that. For example, a data analyst may need to know R or Python, whereas a Hadoop developer must know Java or Scala. Overall Hadoop is related to a programming language.<\/p>\n Hence, with prior knowledge of any programming language, learning Hadoop for beginners becomes easier. Again, that doesn’t mean Hadoop is not for a non-programmer. Many skilled Java professionals also learn R\/Python from scratch. Furthermore, with more and more demand of Hadoop in the market, training or learning these languages are not a tough job today.<\/p>\n This is one area which you must focus irrespective of your future role in Hadoop jobs. Hadoop is all about handling and processing data. Hence, knowledge of SQL query and commands are must to learn Apache Hadoop.<\/p>\n Furthermore, the Hadoop ecosystem has many software packages like Apache Hive, HBase, and Pig, etc. that extracts data from HDFS using SQL like queries. So, if you are not hands-on with SQL query at all, practice it using MySQL workbench or other tools.<\/p>\n While learning Hadoop, it is important to understand various Hadoop terms. Let’s begin with these top 20 Hadoop terms!<\/a><\/p><\/blockquote>\n Before you proceed to learn Hadoop as a beginner, stop for a while and think why Hadoop is so popular and its usability in the technology market. This will help you to understand the core idea behind Hadoop\u2019s functionalities. To achieve this<\/p>\n Get yourself acquainted with the underlying architecture of Hadoop. To do that try to understand how the components like HDFS, MapReduce and Yarn works in the architecture. Once you get the picture of this architecture, then focus on overall Hadoop ecosystem which typically means knowing different tools that work with Hadoop.<\/p>\n The best way to move is installing Hadoop and doing hands-on practice to know more about its practical aspects.<\/p>\n Without knowing the theory, you cannot move more. Hence, following good books, articles and case studies are essential to grab the knowledge properly. There are a lot of good books available in the market that can help you at all stages. Books like Hadoop – the Definitive Guide works like the bible of Hadoop for the beginners.<\/p>\n Want to read some more Hadoop books? Here are the Best Books for HortonWorks Certification<\/a><\/i> with detailed information about the books.<\/p><\/blockquote>\n Once you\u2019re\u00a0familiarised\u00a0with the basics of the Hadoop, you are ready to move to the next levels to learn Hadoop. Let\u2019s follow the best path of learning Hadoop for beginners.<\/p>\n Practice makes a man perfect. The more you practice hands-on with Hadoop, the more you get insights on it. Beginners can download and set up a virtual machine provided by Hortonworks or Cloudera – the two major vendors of the Hadoop industry. The alternate way is to access a pre-installed set up of VM from any training source. Both the way you can access and practice Hadoop and make your Hadoop learning process faster and effective.<\/p>\n Following blogs help one to gain a better understanding than just with the bookish knowledge. There are a good number of big data blogs for beginners available online to provide you a perception of the trends and innovation happening in the field.<\/p>\n Looking for some Big Data blogs to follow? Here is the Best of 2018: A Complete List of Big Data Blogs.<\/a><\/i><\/p><\/blockquote>\n Joining a guided course always helps well and makes learning Hadoop easier for beginners. There are many classrooms and online training facilities available in the market for learning Hadoop for beginners. Moreover, these courses come with additional packages and tools to learn the Hadoop ecosystem.<\/p>\n Ultimately, your goal of learning Hadoop as a beginner is to get a place in the Hadoop industry. If you are in the same line why you don’t follow a certification roadmap? No doubt, a certification from Hortonworks or Cloudera will distinguish you from others with the same skill without any question.<\/p>\n Are you confused between Cloudera and Hortonworks? Let\u2019s find out whether Cloudera or Hortonworks<\/b> <\/a>better for Hadoop certification?<\/p><\/blockquote>\n To conclude, learning any technology is a journey, not a destination. Hence, you should have persistence and motivation to walk in this challenging world of technology.<\/p>\n At Whizlabs, we always help professionals to stay up to date with market trends and technologies.
