@rich Rich and team, Is there a better way to contact you in regards to discovered errors in the Practice Exam? Not sure this is the correct forum for raising such issues as it seems more intended for Q&A. However, the issue noted here also affects the answer for Task 03 item #1. The correct answer should be 30,000. However, the answer shown in the solutions folder is 30,267 which is including records from the 2 weather related files which shouldn't be used until Task 07. ...

#2 of TASK 01 states that you should put the 3 files from the /home/horton/datasets/flightdelays directory into HDFS. However, the flightdelays directory contains 5 files.

Furthermore, when checking the solutions.txt file I can see that the correct command is set to copy all .csv files in the folder to HDFS. How will Tasks such as this one be graded (by command/s used, presence of the correct files in HDFS, etc.)? Would I not receive a PASS for this Task if I moved all 5 files instead of just the 3 with a similar naming convention? ... View more

I am preparing for the HDP Developer Certification and have been unable to find relevant tutorials related to each of the exam objectives. I'm using the labs that are part of the Hortonworks University as well as the official tutorials. I'm aware that the exam objectives list has links to documentation but I'm specifically looking for more hands-on step-by-step tutorials for things such as 'Use WebHDFS to create and write a file in HDFS'. ...
