HDPCD Spark Exam login query


Hi ,

I am planning to take HDPCD spark exam in 2 weeks time. I tried using Hortonworks AWS simulator. If I login as root user on name node (root@namenode, pwd: ‘hadoop’ ) as per instructions am not able to create HDFS folders - it is showing permission denied. But I can create the folder without logging in as root user.

In real exam we have to save the output files on hdfs directory. So I want to know whoever have taken the exam what they have done.

Any help is appreciated.
