Assessing readiness for HDPCD

avatar
New Contributor

Hi there,

I am currently trying to assess whether I am ready to take the HDPCD exam. I have used the AWS instance with the practice exam and have gone through them. I have also installed the standard VM locally to familiarize myself with the Hortonworks components over the past few months. I have also perused other questions on the topic to try and make up my mind on this. I have some experience with hadoop, hive, pig and have used various rdbms for years so most of my issues revolve around the intricacies of the syntax of each tool (e.g., chararray vs string...) rather than what is being achieved.

I am wondering whether the tasks in the sample exam represent (1) the difficulty and (2) the scope of actual exam questions. I know that the exam questions are not the ones in the VM (duh!) but when I am able to complete the tasks within the 2 hour time limit, can I take it as a sign that it may time to give it a shot? I'm just trying to avoid a situation where I think I am ready and arrive at the exam only to freak out because I realize that it is waaaay over the level of difficulty of the practice questions.

Thanks in advance,

Greg

Thanks for the reply! That is exactly my feeling. Because everything is on one page, a search in the Flume docs is easy. Hive is the worst for this... But once you know where you want to get it, it's relatively easy to find it. One question I had was whether when they say "write a hive query", whether that meant that the query had to be one statement? Because I would be able to do it in 2/3 statements but not sure how to do it in only one statement. Of course when you save the query file, it's all executed in one batch but if they only care about the result, I guess it would work either way.

Thanks for the info, I guess I'll practice a bit more and sign up for the exam.

Cheers
