    Hi Durga…I have downloaded Cloudera VM 5.7 which has Spark version 1.6.0 . Would you advise me to keep practicing for my CCA175 on it or Download the appropriate Version to be on par with what will be given during the exam ? Please advise. Thank you.

    Hi,

    Thank you for very useful information on Certifications.

    I have question on how Proficient we need to have on Scala and Python for taking CCA. As I am very proficient in JAVA with 10+ years Exp. Please guide me how much level of learning required on Scala and Python before to get started for CCA learning. And also which one is best either CCA or HDPCD?

     
    • Durga Viswanatha Raju Gadiraju Posted July 18, 2016 11:04 pm

      Certification primarily tests Spark APIs not Scala or Python. Code skeleton will be given and you need to fill with Spark based APIs using Scala for couple of questions and using python for some. As per the 50+ people who clear the certification have acknowledged that my material is good enough to clear CCA certification.

       
      • Praveen Posted July 19, 2016 4:46 am

        Thank a lot for that info Sir. Am gearing up to go through your material on Youtube and crack the CCA.

    ” Python and Spark are gaining lot of momentum. ” errata?, maybe: Python and SCALA are gaining lot of momentum.

    Hi Durga, i have around 10 years of over all exp in IT and working mostly as a backend developer doing programming and production support for Oracle based application, offlately i realized that the Big data technology is getting momentum and this is the right time to transit. I did one course from Edureka as well on Big data and hadoop developer. I tried to apply for many roles in last 2 -3 months but did not receive any interview call. Is it really necessary to have a certification on my CV from cloudera or Hortanworks to get the interview calls?

     
    • Durga Viswanatha Raju Gadiraju Posted August 2, 2016 12:07 am

      Hello Abbas, certification will help little bit. It might not get you job.

      Please watch this playlist for effective job marketing.

    Hi Durga ,

    Very nice compilation ; I would like to ask my ambiguity towards the career in Bigdata .

    Currently i am working as Performance Test Engineer (2+ years ) for one of the Fortune 500 client, choosing performance testing as my career was not in my control (Am not saying testing is less important stream/process ) but am quite interested in development activities whenever i get a chance to develop something , i take it as a opportunity and construct it apart from this i keep reading about the Bigdata domain (due to my interest )usually about Hadoop , MapReduce ,Kafka and other Hadoop Ecosystem Components ;

    My question here is How IT industry accept the profile transitions (say Performance Tester to Developer in Hadoop Ecosystem ) , how can i increase the chances of being selected after a good preparation ? Is certification can help me to get my dream job ?

    Kindly Help .

    I just aced (100%) the CCA-175 exam by studying Durga’s material at http://www.itversity.com/lessons/introduction/. If you want to guarantee a pass, you need to set up a cloudera VM and go through the exercises and make sure you truly understand what is going on in each of them. If you are confident that you understand the concepts, there isn’t too much you need to memorize if you familiarize yourself with the documentation that cloudera allows access to during the exam because you can refer to it for a refresher, but you do need to know what you’re looking for in advance.

    Thank you very much Durga Gadiraju!!

    I see cloudera quickstart 5.4.0.0 & 5.4.2.0 being used in the videos. Current clourdera is 5.8. Since I am learning, I do not like difference in versions. Do you know where I can get the older version?

     
    • Durga Viswanatha Raju Gadiraju Posted September 12, 2016 5:26 am

      You can use latest versions as well. There is no harm in it. If you are preparing for CCA175, do not focus on data frames or spark sql and you are good to go.

    Hi Durag,
    I’m interested to enroll in BigData training ongoing in this month. I’m a java resource , i dont have any knowledge on BigData, enrolling into ongoing BigData training will help me to do CCA certificate? or get some basic knowledge then enrolling on next coming training will be good .
    Hoping for your reply & support for my learning .

    Hi Durga,
    Thanks for your videos, they are so useful. Just i started practicing them to get CCA Spark and Hadoop Developer.

    I have question for you, I’m pure Data analysts. I’m working with SQL Server/Oracle for over 15 years. Now i’m wondering if I need to know Scala or any other development language to get CCA certificate. Or i can go for Another course which is more suitable for Data analyst like me.

    Thanks,
    Damun

     
    • Damun Posted November 7, 2016 5:35 am

      Hi Durga,

      Didn’t get any reply from you. Hopefully there is nothing wrong with my question.
      I found CCP Data engineer more suitable for me. It’s more focused on Hive, Flum, Sqoop and Hadoop. But I don’t understand why it’s more advanced certification than CCA. even number of Videos you provided for CCP is less than CCA certification videos.

      When ever you can, please let me know which topic is more convenient for Data analyst.

      Heaps of thanks for your time and wonderful videos my friend.

      Cheers,
      Damun

       
      • Durga Viswanatha Raju Gadiraju Posted November 7, 2016 11:40 pm

        Hello Damun,

        sorry for delay. CCP Data Engineer is not advanced certification than CCA, but it is tougher than CCA. As Data Analyst you should either go with CCP Data Engineer or HDPCD with out Java. You get practice exam for HDPCD and it cover Pig, Sqoop, Hive, Flume etc.

        Regards,
        Durga Gadiraju

    Hi Durga,

    Your videos are very helpful in understanding the concepts of Hadoop.

    I want to make a career shift from Mainframe (3+ years exp.) to hadoop , I have also uploaded my resume on naukri(2+ yrs on hadoop) but still , I got very few calls , Please let me know what should be the included in the resume to get more calls for interviews(as hadoop is a hot skill in market, i was thinking of more calls).

    Please also let me know will getting a certification help me in getting more interview calls?
    and is investing in a certification a good decision, so that I get a hadoop job .

    Which certification should I go for(with a vision of getting a job) ?

    1)Hortonworks
    2)Cloudera
    3)MapR

    Please clear my doubt.

    Thanks very much in advance.

    Hi Durga Sir,
    Just been very confused whether does one needs to know Python or Scala prior to attempting the CCA Spark and Hadoop Developer certification as it includes many questions based on PySpark and Spark with Scala?
    Do we actually learn Python first or the vice versa or just the CCA Spark and Hadoop Developer playlist created by you?
    Many thanks in advance for all of the amazing material.

     
    • Durga Viswanatha Raju Gadiraju Posted November 7, 2016 11:42 pm

      Yes, you need to know both Scala as well as Python. They will give code snippet in both programming languages (2 each) and you need to fill in the blanks with Spark APIs.
