							 @Gurjinder Singh - to fully be prepared for the exam, you should be able to perform all of the exam objectives listed here:  http://hortonworks.com/training/class/hdp-certified-developer-hdpcd-exam/  I highly recommend also taking the practice exam. The details are on that webpage above. It uses an environment similar to the real exam and contains tasks similar to the real exam, and it's a great way to test your knowledge and see how ready you are for the exam.  Keep in mind the practice exam does not cover every exam objective, so use it only as an aid to prepare. Like I said first - to be fully prepared make sure you can perform all of the exam objectives listed on our website. If you need coding experience and are looking for ideas, check out the tutorials on our website:  http://hortonworks.com/tutorials/

							 You ask a good question, so I tested it out. I just ran through the wizard to enable NN HA, and then I ran the following command from Step 15:  hive --config /etc/hive/conf.server --service metatool -listFSRoot  The FS root was not the old value (which the documentation says it will be), but instead it was set to the correct value of my new Nameservice ID. I tested this using Ambari 1.7, so if you are using at least 1.7 you can ignore that last step.  I have a hunch that the documentation page is out of date and just needs to be updated.

							 @Gurjinder Singh Make sure you have a table in Hive named 'emp1' in the 'default' database.

							 @Saurabh Singh    The real environment looks the same as the practice environment   The tasks are displayed differently though - on the real exam, the tasks appear in a separate pop-up window that you can move around  Each task will tell you where to save your answer. For example, Task 1 might tell you to save your script in a file named /home/horton/solutions/task1  The answers are evaluated by the output. There are always different ways to solve problems in programming. It is not the code we are interested in - it's the result. You need to execute your code on the real exam and it needs to generate the desired output described in the task instructions. (If a task has no output, it is immediately marked as wrong.)  Each task is worth 1 point and it is either correct or wrong - there is no partial credit.   The current HDPCD exam has 7 tasks and you need to get 5 correct to pass. (This is subject to change at any time.)

							 To fully prepare for an exam, I recommend two areas of focus:   You should be able to perform all of the exam objectives listed on our website  You should attempt the corresponding practice exam    Taking the practice exam alone is not enough - it is only meant to give you an idea of what the exam environment is like and what the tasks are like. To be fully prepared, you should be able to perform every task listed in the exam objectives.  Good idea! I like the idea of collaborating and sharing ideas for exam prep, as long as everyone is careful not to share actual exam details - which would be a violation of the candidate agreement. The best way to collaborate would be here on the Hortonworks Community Connection and tagging all posts with "HDPCA". I will start tagging exam posts as they come in.

							 Good question. If you look at the current exam description, it uses Ambari 1.7 which does not have Views for Pig and Hive:  http://hortonworks.com/training/class/hdp-certified-developer-hdpcd-exam/  However, the HDPCD exam is about to be updated to HDP 2.3 with Ambari 2.2, so anyone preparing for our exams - make sure you know which version of Ambari and HDP your exam will be on. This information will always be available on our website:  http://hortonworks.com/training/certification/  That being said, your exam is graded by the output of your code, so it is irrelevant how you write the code. You can use any text editor and run the scripts in any way you choose.

							 Hi @Raghunadh Chellinki  Sorry about the confusion. The option for "ec2-classic" is only available if your Amazon account is more than 2 years old. If you had to create a new AWS account, then you will have to launch your instance into a new VPC. Just make sure you enable "Auto-assign Public IP address" - then everything will work fine from there.  Let me know if you have any other questions.  Thanks,  Rich

							 You do not run the Sqoop command as root on the namenode. Run the Sqoop command as the "horton" user on the Ubuntu client.
