  2. Dear Krish,
    Thank you so much for the guide. I tried to attempt exam on 22 november but I failed. Only 3 problems were correct.
    There was a question about setting Heap size which I didnt understand. They gave us some amount of Ram and asked to calculate and configure heap size. Can you help me what is this.
    Also there was a problem related to Kafka configuration which was configured wrong before but I was not able to solve the error.
    Can you guide me what should I do for preparing exam.
    Also there was a question about making groups for role.
    Can you help me.
    Thanks in advance
    Thanks in advance

    1. Hi Syed,

      Sorry to hear about that.

      For Kafka configuration, first you have to download and activate the Kafka parcel, then proceed to add the Kafka service. Then kafka brokers will be started. If you encounter any issues in starting Kafka broker, then look at the logs to see what’s the issue and troubleshoot accordingly.
      One of the common issue is the heap size of Kafka broker. Go to kakfa – configuration – search for ‘heap size’ and change it to recommended value.

    2. Hello Syed !!

      Excuse me for the delay in replying to your comment. My suggestion for preparing “CCA131” exam, make use of the official documentation,read it no shortcut, as well use this blog for practising cloudera official curriculum to take exam. If you can recollect what questions you come across in your last attempt and analyse them to get solutions. I hope this will help you in clearing in exam. Practice well. ALL THE BEST!!
      Thanks

  3. Hi Kannan- You’re doing a great job. Is it possible to give an idea of what kind of questions are asked related to Sqoop and Flume?

    Regards.

  4. Hi Friends,

    Thank you much for the guide. I tried to attempt exam recently but unfortunately, I got failed and 6 question was correct.

    As per my Understanding, This exam question was not high level but its all tricky questions.
    Linux administrator skill is more useful so first prepare the Linux basic command.

    There was a question on HDFS YARN configuration change parameter, Resolve the application failure issue, dynamic pool configuration, Regular expression, snapshot related question.

    My suggestion for preparing “CCA131” exam, Install the Cloudera on a laptop and practice well as per the syllabus and this blog. I hope this will help you in clearing in exam. ALL THE BEST!!

    Thanks

  7. How do you calculate total allotable memory on a name node, where the total available memory is 41 GiB NonDFS Reserved is 7.2 and the total usage/consumption multiplier is 1.4 ?

    1. Hi Vic,

      Can you clarify what does it mean ” total usage/consumption multiplier is 1.4 “.

      By default, namenode memory + os memory = node memory. So here in this case, maximum allocable for nn is 33.6

  8. Hey Kannan,

    I have cleared CCA131 couple of days back, I must thank you for your writings and guidelines, it indeed helped me to go further and give it a try. Appreciate your efforts.

    1. Hi Vin,
      That’s awesome to hear. Glad that I could be of some help but full credits to your hard efforts.
      Wish you all the success in your future projects.

  9. Dear Kannan,
    Thank You very much for this website and blog…
    I had a question in the exam:
    Node RAM is 32GB, nonDFS reserved memory is 6.2GB. Heap size 1.3X
    Cant remember exact question…
    Couldn’t answer the question correctly.

    Would be really helpful if you could explain how this question is to be solved.

    Thanks in advance..
