Hello, Robert, Normally is a couple days, up to 5, to receive grades from proctoring company. Let me check on this particular one and see if there was an issue in the grade transmission. Also, just to double check, sometimes these emails are caught in your spam folder. I will email you in a few minutes.

No worries, sorry if I misunderstood. The level is the same.Of course the questions and datasets are different but the tasks are similar in nature. If you comfortable finish all tasks in the practice, I have a high level of confidence you can pass the actual exam. try finishing under 2 hrs to best simulate the actual exam. Hope that this helps.

The actual exam is hosted by a proctoring company so it adds a wrapper for chat (with the proctor). The screen may look a bit different because of the wrapper, but the underlying cloud VM is the same in format and HDP version. More info can be found in http://hortonworks.com/training/certification/hdpcd-certification/ Hope that this helps

You have to convert the DF to a table, then save the table like: myDF.registerTempTable("myTempTable") val myDFTable = sqlContext.sql("SELECT col1, col2, col3 FROM myTempTable WHERE col2 > 1000") myDFTable.map(x => x(0) + "," + x(1) + "," + x(2)).saveAsTextFile("output.csv")

Yes, thats what I figured. I will fix. Thanks for the feedback.

OK. I understand. Thank you for bringing that to our attention. I think that the documentation probably moved. I will review and update. Thanks again

Thanks for the feedback. I will check the links. Meanwhile I attached the actual datasheet pdfs for your reference. Cheers

Hello, Abhijit, The exam does not specify which method, that is up to you, as long as the output is in the correct format and # records. Hope that this helps

Hello, Abhijit, Yes the exam instructions ask you to save the scripts in a folder under the current user directory in the exam Desktop. The exam will tell you the exact location of where to save it. Normally you would write your script using vi or gedit (available in exam environment) and then save it in the correct location. Hope that this helps

Not sure why you are getting that link. What was the page that you were accessing the exam datasheets from? I do not think that they are under docs.hortonworks.com Can you try accessing from here: http://hortonworks.com/training/certification/ --> http://hortonworks.com/training/certification/hdpcd-certification/ In any event, I am enclosing the sheets: datasheet-hdpcd-java-22.pdf certdatasheet-hdpcd-24.pdfdatasheet-hdpca-23.pdf
