Do I need to learn Java for Hadoop?

People regularly ask me if it’s necessary to have Java development abilities in order to type in the interesting world of Hadoop. When I begin to describe, I’m often met with a frustration and a feeling of restriction upon studying that Java and Hadoop do, in fact, go hand-in-hand. Let me start by saying that the response to the query “Do I need to know Java to understand Hadoop?” is not a easy one. But I digress; the long run of Hadoop is shiny, and moving ahead, no specifications should be seen as restrictions or hurdles, but rather as ways to enhance your abilities and become more professional in your work. As you make your way through this, Hopefully I will be able to describe your issues, and help get you on your way to quality within Hadoop.

To get to the base of this query it’s necessary to look into the record of Hadoop. Hadoop is Apache’s open-source platform; designed to shop and procedure loads of information (orders of petabytes). It happens to be designed in Java. (Personally, I see the terminology choice as merely random.) Hadoop was initially designed as a subproject of “Nutch” (an open-source search engine). It was later designed and would go on to become Apache’s most important venture. At the time this was all occurring, the Hadoop designer group was more relaxed with Java than any other terminology.

Let’s proceed to must program

Hadoop resolves large information systems difficulties through the mature idea of allocated similar handling, but techniques it in a new way. Hadoop provides a structure to build up allocated programs, rather than fix every problem. It requires away areas (such as device problems, allocated procedure control etc.) of saving and handling the information in a allocated atmosphere because they build the primary components: HDFS and MapReduce, respectively.

HDFS is an allocated data file program that controls information storage space. It shops any given computer data file by breaking it into set dimension models known as “blocks.” Each prevent is saved on any device in the group. It provides high accessibility and mistake patience through duplication (think of it as duplication) of these prevents on different devices on the group. Regardless of all these complications, it provides a easy data file program abstraction so that the consumer need not worry about how it shops and operates.
