Hi all, I am new to Hortonworks, my task is managing our cluster in office, however we plan to mount all other hard drives on our server under /data0 /data1 /data2 and so on. My question is will Hortonworks automatically create hdfs in those folder? I have done a single node test installation, I notice the /hadoop folder is created.

Hi there,
I just enable Kerberos on my test cluster, however after enabling kerberos, I am not able to create /user/test directory anymore due to permission error.
hadoop fs -mkdir /user/test mkdir: Permission denied: user=admin, access=WRITE, inode="/user":hdfs:supergroup:drwxr-xr-x
Anyway to fix it?
Thanks
