Hi experts,
As the root user, I am trying to delete a directory in HDFS which was created by root.
However, when I try to delete it, it says "Permission denied: user=root, access=WRITE, inode="/user":hdfs:hdfs:drwxr-xr-x"
Why does it say permission denied on "/user" when I am trying to delete the directory "/tmp/root/testdirectory"
The error message is below.
[root@test02 ~]# hdfs dfs -ls /tmp/root/
