Do not discuss certification exams tasks in a public forum. This violates the agreement you accepted when you registered for the exam. If you have any questions or issues, please send an email to certification@hortonworks.com

No - there is no Java on the HDPCD exam. It is Pig, Hive, Sqoop and Flume, and to be fully prepared you should be able to perform all of the exam objectives listed here: http://hortonworks.com/training/certification/hdpcd-certification/

I wonder if they were just having system errors at the time you tried to login. I just logged in fine. If you are still having the issue, you will need to contact PSI. They will be able to assist: http://it.psionline.com/contact-us/support/

There is no IDE available on the Spark exam. You can use pyspark or spark-shell to execute your code. You do NOT have access to google or the internet. You DO have access to the Spark doc pages, the Python and Scala doc pages, and the Hortonworks documentation as well. There is currently no practice exam for the Spark exam. If you need experience writing Spark applications on HDP using Python or Scala, I recommend downloading the Sandbox and working through the Hortonworks Spark tutorials.

Just a couple of helpful tips: The tab is the default delimiter, so you can just use LOAD '/user/horton/flightdelays_clean' The answers to the Practice Exam tasks are on the Ubuntu client in the /home/horton/solutions folder.

Thanks - this is exactly what is happening. FYI: I think it also affecting Pig. Is there a way to set the timeout to be a much shorter value?

I am running HPD 2.4.0.0 installed with Hive 1.2. If I exit the Hive CLI using Ctrl+c, then try to run Hive again immediately, it takes about 10 minutes for the Hive prompt to appear. It just hangs right here: root@node1 bin # hive
WARNING: Use "yarn jar" to launch YARN applications.
Logging initialized using configuration in file:/etc/hive/conf/hive-log4j.properties
Any thoughts on why this may be occurring? BTW, if I exit Hive using the "exit;" command, everything is fine and I can startup Hive again right away with no issues.

List the contents of the following folder: # /usr/hdp/current You will see the version number of HDP (plus the version of every component). For example, I have HPD 2.3.0.0-2557 on the machine below: [root@namenode ~]# ls -la /usr/hdp/current/

Got it! No - that's not really anything we have that is in any kind of public-facing format.
