  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
      krish
