Why Big Data Matters!!

Big Data has become a popular term to describe the exponential growth and availability of structured and unstructured data. With increasing amount of digital data, it has become essential to find a technology that can be used to analyse this data. The real big question is ‘Why Big Data should matter to you?’

You can watch the following presentation for more information on this:

Topics Included in the Presentation:

  • Big Data
  • Big Data and Hadoop
  • Why Hadoop?
  • Hadoop: The future of Data Management
  • Hadoop: Job Roles
  • Hadoop: Growth and Job Opportunities

Need for Hadoop:

Hadoop is changing the dynamics of large scale computing. Its impact can be pointed to four salient characteristics – Scalability, Cost Effectiveness, Flexibility and Fault Tolerance. Almost 80% of the data floating around is unstructured and a majority of it is left unused or analyzed. Hadoop offers an affordable and an effective alternate to analyze this data. This makes Hadoop the favorite and popular among Big Data technologies.

  • Amit Rawat says:

    Hi Edureka,i am having 2 years of experience in ETL support environment (mostly Monitoring)and want to take up the Big Data and Hadoop developer Training. I want to move from the support backround to Development ….although i have a sound understanding of core java and collections framework so could you please tell how hard it would be make this transition with such a background and would there be any opportunities for people coming from support background like mine and would it be wise to make such a choice(actually i really dont have any at the moment given the kind of thing i am in right now).

    • EdurekaSupport says:

      Hi Amit, Hadoop is a relatively new field and organizations are looking for professionals with knowledge and some hands-on experience in it. You professional experience along with the hands-on experience will help you land a job. You can gain hands-on experience by working on projects during your training at Edureka. The only prerequisite for learning Hadoop is knowledge in Core Java. Since you have a sound knowledge in Java, learning Hadoop should be fairly easy and will definitely give you an edge.

    Sir I have done BCA, I am Fresher, Can I apply for this course and what is chances for jobs

    • EdurekaSupport says:

      Absolutely Khwaja! Even people in their final years of education are considering Hadoop. The reason being, a lot of companies are looking for freshers in Big Data space. The prerequisite is core Java, I’m sure you must be having knowledge on the same. This makes it easier for you to learn Hadoop. What we are seeing as of now is just a start and there is a lot of potential for professionals who will be the early movers in Big Data space. You can refer to these articles for more information:

  • Mayank says:

    I want to know whether programmer can see intermediate result between Map and Reduce function or not?

    Please give that proof also to support your answer.

    • EdurekaSupport says:

      Hi Mayank, The programmer cannot see the see the
      Intermediate result between Map and Reduce function. This is because, after processing input in mapper the result of the map is not directly
      passed to the reducer there is one more phase called sort and shuffel phase
      Sort and shuffel phase has 2 phases:

      • Copy phase

      • Sort phase

      These two are not visible to the programmer as this task is internally done by the
      frame work.
