Hello, thank you for the feedback. For specific issues while taking exams, these are better answered directly at certification@hortonworks.com. I also already replied to you there regarding your specific situation. However, for anyone that is planning to take a Hortonworks exam in future, I want point out that >90% of the reported exam issues can be tracked down to one or more of the following: 1 Network Bandwidth needs to be 20/3 Mbps down/up or higher for best performance. 2 ALL Anti-Virus software needs to be disabled during the exam. 3 Latency Due to distance to the exam cloud site. We try to launch the exam closest to where your examslocal.com registration country is. If your registration country is different from where you actually take the exam, depending on where it is, there could be tremendous delay observed. All these are stated on the exam FAQ pages as well as registration emails from examslocal.com as well as Compatibility Checks before the exam.

There is no practice exam for the HCA but we recommend taking our Essentials course https://hortonworks.com/services/training/class/hadoop-essentials/ and of course, fully reviewing the Exam Objectives: https://2xbbhjxc6wk3v21p62t8n4d4-wpengine.netdna-ssl.com/wp-content/uploads/2016/08/ExamObjectives-HCAssociate.pdf Thanks

Hello, Samir. For the real exam, we normally run this on instances with 30GB RAM. I would not recommend anything lower than 16GB RAM. Even our downloadable sandbox recommends 16GB nowadays. You can use your instance then stop it (but not terminate) to avoid extra charges. Hope that this helps.

Hello, Venkata. We are still in the planning stage for the new certification. We do not yet have dates for the release, however we will make a public notification with ample time so you can prepare. I probably expect some overlap between the two certifications. Thanks

Hello Voruganti. The first step, of course, is to pass the HDPCA itself. After that, please write to hwuniversity@hortonworks.com and a Training Manager will contact you with the details on how to become a trainer. Thanks

Hello, Mauro, I am assuming that you are using the Practice HDPCD Exam AMI to create an EC2 instance. What is the AMI-ID and region of the instance? In general, lease follow these steps: ssh to instance as the ubuntu user after you are inside the instance, then do ubuntu@cloud-instance:~$ sudo su - root@cloud-instance:~# service docker status
docker start/running, process xxxx if you do not see docker running, then root@cloud-instance:~# service docker start root@cloud-instance:~# docker ps

There is no set date for the expiration of a Hortonworks Certification.
Normally when a new certification format is implemented, it is desired to have the new certification over the old one and the new certification takes precedence.
However, an overlap period will be considered to allow candidates to come up to speed and obtain the new certification. We will announce any new certification in the future and give you ample time to prepare for it.

Hello, Sri. Normally the service should not be in maintenance mode if there are tasks that need to be completed on that service (like HDFS, YARN, HIVE, etc). If you have configuration/troubleshooting tasks around that service, you should be able to complete that task and restart the service in non-maintenance mode to ensure that the changes you made are working. If the service does not start properly because of a configuration issue, then the task will be wrong. So, as a norm, make sure the service is able to run in non-maintenance mode. Hope that this helps

Hello, Abhijit, It normally takes a few days (2-5) to receive grades from proctor. You will receive an email when the grades are processed on our end. The email will state if you passed or fail. If you passed, then additionally you will receive a link to a e-badge from BadgeCert (https://badgecert.com). We do not have a hard copy certificate as most people prefer an electronic badge. Hope that this helps.
