> The HDFS safe mode check workaround introduced by HBASE-4510 performs a 
> {{FileSystem.setPermission()}} operation on the root directory ("/") when 
> attempting to trigger a {{SafeModeException}}.  As a result, it requires 
> superuser privileges when running with DFS permission checking enabled.  
> Changing the operations to act on the HBase root directory should be safe, 
> since the master process must have write access to it.
