[jira] [Created] (HADOOP-11224) Improve error messages for all permission related failures

Harsh J created HADOOP-11224:
--------------------------------

             Summary: Improve error messages for all permission related failures
                 Key: HADOOP-11224
                 URL: https://issues.apache.org/jira/browse/HADOOP-11224
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
    Affects Versions: 2.2.0
            Reporter: Harsh J
            Priority: Trivial


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

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

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

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

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