You can set fine-grained security access policies for accessing component resources through the permission plug-in of the component. If Ranger authentication is not required, the cluster administrator can manually disable Ranger authentication on the service page. After Ranger authentication is disabled, the system continues to perform permission control based on the role model of <span id="admin_guide_000415__text154091129192818">MRS</span> Manager when accessing component resources.</p>

<p id="admin_guide_000415__p1328751611431">In a cluster upgraded from an earlier version, Ranger authentication is not used by default when users access component resources. The cluster administrator can manually enable Ranger authentication after installing the Ranger service.</p>
