There are issue but you can overcome them with some tips: 1. The main problem in the exam is the text size. I suggest you to get good resolution monitor. Get Familiar with how to increase the text size in the browser and terminal. To increase the size of text in the browser use ctrl + or go to the options button on the right corner of the browser and look for zoom option. For increasing the text size in Terminal you have to look in the terminal options to do that. i don't remember this. If you can do this you are good to go. 2. Write scripts in the files and execute them rather than executing everything in the shell line by line. 3. while you execute one script start writing the next script. open terminal with multiple tabs and dont close the tabs until you get the right output.

It is not /user/hdp it is /usr/hdp/current or try to cd
/usr/hdp/2.4.xxx/flume/ and look for a version number. This location is
on local file system not on hdfs. As you are using sandbox it should be
the same location.

I have recently took my hdpcd exam. I have faced so many issues. The exam screen in the chrome browser was very small that i can barely read anything. I have to adjust the text size of the browser and i had a 30 mbps line but i still had a lag. I had the pasting problem in pig. As a result i got only time to attempt only 5 questions. i had a very bad time taking the exam. I have failed the exam. Is there any chance for getting credit to retake the exam.
