    Hi JJ,

    Great blog, i would say. Though i have been working as a Senior project manager and with 17 years of IT Experience. Currently, I am working in a E-commerce company and spent large time managing project issues and risk and cost, emerging technology has always been an interesting area for me. I have been following GFS and BigTable for sometime 2 years ago but could not take it up further. Recently with tremendous opportunity in the Big Data Anlaysis space, Hadoop along with other contrib such as Hbase, Hive, Pig, Scoop, Cassendra, NoSQL and the count is endless with Karmasphere and Cloudera in the IDE space for these technology.


    As like you, i would also like to appear in the Hadoop Developer training and certification (Cloudera Certification), please let me know more on this.

    I have been following, Following book
    1. Hadoop - A definitive Guide, Second volume
    3. hadoop - A quick Introduction (IBM site)
    4. Hadoop in Action - by Chuck Lam (Sample chapter 10 - Programmming in PIG)
    5. Article on Big data Analysis by Ravi kalakota (Search in Google. He is excellent writer on Predictive analysis and other form of Big Data Analysis
    6. Storm - The big data analysis tool from twitter.
    7. Understaning Big Data - Analytics for Enterprise Class Hadoop & Streaming Data.

    Hello Sanjay

    Thanks for your comment.

    You having so much industry experience , would love to learn lot of things from you.

    With Reference to Hadoop , you have already covered all the group preparation by reading those books.

    I will also go through few links you mentioned.

    Few days back i had talk with Cloudera people , they said just before start of VUE exams they would release few more details about exam.

    Otherwise syllabus as i already mentioned would be enough

    Hadoop Computing Environment
    Hadoop Distributed File System
    MapReduce
    Hadoop API
    Hadoop Ecosystem

    Regards

    Hi guys,
    I am planning to go for it too, but just curious to know how will it help to go forward in career and how much weight does this certification carry w.r.t. the job opportunity in today's market. BTW I don't have any domain exp. of file systems/big data analytic, but interested to know and pursue further.

      Hello Roopa ji,

      No worries better luck next time.You can check Cloudera website if they give next turn free or not?

      Okay coming to how to prepare.

      What have you read already ? I would reccomend you to read the Definitive guide book atleast 2 times. Since options are confusing and very similar so you might end up choosing wrong one if we are not through with the concepts. Follow the topics given in Syllabus and plan your schedule accordingly.

      And dont worry for failure its very common :)

      Good luck

      Hello Ankit,

      Being Admin you are already half way to move towards Hadoop Adminstration.

      I would suggest you to grab Hadoop Definitive guide and start reading about it. Dont worry for certification as of now , that you can clear easily.

      Hi Somi,

      Few questions i would ask to you.

      Is your company sponsoring your certification fees?

      Yes

      Then go for any doesnt matter

      No

      Go for Hortonworks

      Last but not least its knowledge which matter the most rather then certification. So just work hard and try to learn and dont worry for exam it would be cake walk when you give it.

      Both Hortonworks and Cloudera have equal reputation.
