> 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.
