>                 Key: HADOOP-3273
>                 URL: https://issues.apache.org/jira/browse/HADOOP-3273
>             Project: Hadoop Core
>          Issue Type: Improvement
>          Components: dfs
>    Affects Versions: 0.16.0
>            Reporter: Konstantin Shvachko
>
> There is a name collision in 
> org.apache.hadoop.fs.permission.AccessControlException and 
> java.security.AccessControlException.
> Since  java.security.AccessControlException is not an IOException we cannot 
> throw it directly as we do with FileNotFoundException.
> Therefore, the only choice is to rename the hadoop AccessControlException to 
> e.g., PermissionException (or AccessDeniedException).
> To provide compatibility we can inherit PermissionException from 
> AccessControlException, and deprecate the latter.
