Hi, Mondi! The msg you are getting is telling that user devuser does not have permission to write to the root (/) HDFS folder. This is normal, and just like a Linux FS. If you create a folder in HDFS and make your local unix account the owner, you can use that folder as you. If you want to create objects in hdfs /, you need to become the superuser, hdfs. Example: # create your folder
$ sudo -u hdfs hdfs dfs -mkdir /user/devuser
# make devuser the owner:
$ sudo -u hdfs hdfs -chown devuser /user/devuser You first elevate to hdfs, then run the hdfs dfs command. This wil create your personal directory in /user and make you the owner. Now, when you run hdfs commands as devuser, you will have permission to modify objects in that folder. CAREFUL: elevating to hdfs is like becoming root in linux. You can do a lot of damage if you make a mistake.
