Aaron T. Myers commented on HADOOP-8343:
----------------------------------------

+1 pending Jenkins. One tiny nit:

{noformat}
+   * If <code>hadoop.security.instrumentation.requires.admin</code> is set to 
FALSE
+   * (default value) it returns always returns TRUE.
{noformat}

One too many "returns" in the sentence above.

> When using authorization for the daemons' web server, it would be useful to 
> specifically control the authorization requirements for accessing /jmx and 
> /metrics.  Currently, they require administrative access.  This JIRA would 
> propose that whether or not they are available to administrators only or to 
> all users be controlled by "hadoop.instrumentation.requires.administrator" 
> (or similar).  The default would be that administrator access is required.
