  19. Anupam says:

    Hi Admin,
    First of all thanks for such a informative portal!

    I am a Hadoop learner working at USA. I know there are plenty of opportunities in hadoop without any doubt. The only problem I am facing is to get hands on experience. I mean writing few programs and working in actual production world is quite different you know. Also, I feel we learn things more if we make our hands dirty in code. Few ppl have suggested to do something on your own and upload in Github or somewhere to prove you have knowledge. But, how much that works?

    What do you think we have options to get hands on experience ? The issue is while you are at onsite/USA , employers never take chances to experiment with someone not having prior knowledge on the technology….

    Thanks,
    Anupam

    • Admin says:

      Hello Anupam,

      There are plenty of options to get hands on experience.

      We would suggest you to start with Hadoop Basic course, which will make you familiar with Hadoop Basics, together with writing your simple examples in Hadoop Sandbox system offered by Hortonworks.
      At the end ofthe Hadoop Basic Course, there is one real world use case which covers analyzing unstructured files(data), loading data into HadoopHDFS and using Hive to aggregate the data and finally use it in business client to analyse the result from different perspective.
      We believe you can kickoff your Hadoop Journey, with the Hadoop Basic Course

      Best Regards

      Considering the huge requirement of Hadoop Developers now-a-days, you have a pretty good chance.

      No doubt your choice on moving Hadoop is really good. The cost and time which is involved in extracting data from mainframe-based applications has always become a point of concern. With Hadoop problems are solving now by finding more-effective ways to bring mainframe-hosted data and Hadoop-powered analysis closer together.

    Nice post! Apache Hadoop is a parallel distributed processing middleware technology which is applied across various industry verticals to perform Big Data analytics. Most data gathered by organizations are unstructured data. Hadoop-based applications are hence applied by organizations that need real-time analytics from data such as audio, video, email, machine-generated data from a multitude of sensors and data from external sources such as the Internet and social media. Hadoop-based applications are widely applied across business verticals with strong web-based business process for various customer related analysis such as clickstream analysis, marketing analytics, processing machine generated data, processing digital content and web text processing.
