My experience was not good with HDPCD exam which was scheduled for today (6-8 PM CST) .Please refer below issues which occured during the exam:
1- > Window was not scrolling due to slow connectivity.
2- > I was not able to navigate between windows.
3-> Window was not opening when i was clicking on it.
4-> I informed to instructor as well about this scenario.
5-> There was a situation when i typed the letter and it was not appearing over the box for at least 3-4 minutes.
Currently I am waiting for my result but it was a really very bad experience for me.
I don't have any hope with the result .There was lot of validation was require from my end which i was not able to do because of these issues
Please let me know what further option is available.
I would use Hortonworks contact us support page for questions around certification and options you may have. Someone should be in touch with you
