HttpServer.isInstrumentationAccessAllowed介绍

[英]Checks the user has privileges to access to instrumentation servlets.

If hadoop.security.instrumentation.requires.admin is set to FALSE (default value) it always returns TRUE.

If hadoop.security.instrumentation.requires.admin is set to TRUE it will check that if the current user is in the admin ACLS. If the user is in the admin ACLs it returns TRUE, otherwise it returns FALSE.
[中]检查用户是否具有访问检测servlet的权限。
如果hadoop.security.instrumentation.requires.admin设置为FALSE（默认值），则它始终返回TRUE。
如果hadoop.security.instrumentation.requires.admin设置为TRUE，它将检查当前用户是否在管理ACL中。如果用户在管理ACL中，则返回TRUE，否则返回FALSE。
