MySQL works fine on the practice exam. It is not running on the Ubuntu client - mysqld is running on the namenode server, so if you want to view the databases and tables in MySQL then you must ssh onto the namenode: $ ssh root@namenode (password is hadoop) # mysql --user=root --password=hadoop Let me know if that answers your question. ...

@Vidya SK The connection URL for the practice exam is: --connect jdbc:mysql://namenode/flightinfo There is nothing special you need to do prior to running the Sqoop command. The environment is configured properly for Sqoop to connect to MySQL. The entire working Sqoop command can be found in the /home/horton/solutions/ folder. ... View more

@Vidya SK - each task on the HDPCD exam is worth 1 point and it is either correct or wrong. There is no partial credit. If a task has subtasks - the entire task is still worth 1 point. Keep in mind the practice exam is meant to get you familiar with the environment, and to also give you an idea of the types of tasks on the real exam, but it is not perfectly exactly reflective of the real exam. For example, in the practice exam all the tasks depend on each other, while on the real exam the tasks are completely independent. To fully prepare for the HDPCD exam, you should be able to complete all of the exam objectives listed on our website. That should be your main focus while preparing and studying for the exam. ...

@Daniel Hendrix Using the Hortonworks Community Connection is perfect - it allows others who may have similar issues to find answers quickly. I appreciate you sharing these typos. It looks like there is a minor disconnect between the data files in the practice exam and the solutions provided. We will take a look at this the next time we update the practice exam. Keep in mind there are two main goals of the practice exam: To become familiar with the environment that the real exam uses To get a sense of the types of tasks you will be asked to perform It is not meant to be an all-inclusive study guide. For a candidate to truly be prepared for the HDPCD exam, you should be able to complete all of the tasks listed in the exam objectives: http://hortonworks.com/training/class/hdp-certified-developer-hdpcd-exam/ Let me know if you have any other questions or issues. Thanks, Rich ... View more

That is correct. We are not interested in "how" you do something - only that you can accomplish it. For example, you may be asked to write a Pig script that satisfies a set of criteria. We don't care what your code looks like, as long you use Pig and the output satisfies all the given criteria. ... View more

That sounds like a typo on the practice exam - thanks for pointing it out. The key factor in grading exams is the result (after verifying that you completed each task using the specified framework). In each task on the exam, you will be asked to write some type of code or script and execute it. Each task is worth 1 point and it is either correct or wrong. There is no partial credit. You must execute your code and it must generate the desired output in the desired location in order for a task to be marked as correct. Please let me know if you have any other questions.

Hi @Daniel Hendrix You are correct - you should be able to start a Flume agent from the command line. The docs show how to do this: https://flume.apache.org/FlumeUserGuide.html#starting-an-agent You also need to know how to configure a memory channel, which is also demonstrated in the docs: https://flume.apache.org/FlumeUserGuide.html#memory-channel I would recommend going through the same tutorial that you found here: http://hortonworks.com/hadoop-tutorial/how-to-refine-and-visualize-server-log-data/ Within that tutorial, configure a memory channel and try starting it from the command line. Let me know if you have any issues along the way and I'll be glad to assist. Thanks, Rich Raposa Certification Manager ... View more
