----------------------------------
+1 I tried {{mvn compile findbugs:findbugs}} and the patch does remove the
warning.

> HDFS-6326 introduced the {{FsAclPermission}} class as a subclass of
> {{FsPermission}}. This triggered a findbugs warning due to not overriding
> {{equals}} and {{hashCode}}. It's intentional that these methods are not
> overridden. We can override them to call {{super.equals}} and
> {{super.hashCode}} to suppress the findbugs warning.
