Description

If a bad file create request fails, you get a juicy error self-describing the reason almost:

Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): Permission denied: user=root, access=WRITE, inode="/":hdfs:supergroup:drwxr-xr-x

However, if a setPermission fails, one only gets a vague:

Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): Permission denied

It would be nicer if all forms of permission failures logged the accessed inode and current ownership and permissions in the same way.
