Access Control


A goal is to support authentication and authorization seamlessly between the Kylo applications and the Hadoop cluster.


Authorization within Kylo will use access control lists (ACL) to control what actions users may perform and what data they may see.  The actions that a user or group may perform, whether to invoke a function or access data, are organized into a hierarchy, and privileges may be granted at any level.

Users and Groups can be updated using the Users and Groups pages under the Admin section in Kylo.


If groups are enabled for an authentication plugin module, then user groups will be provided by the external provider and may not be updatable from the Users page.

Default Users and Groups

When Kylo is newly installed, it will be pre-configured with a few default users and groups defined; with varying permissions assigned to each group. The default groups are:

  • Administrators
  • Operations
  • Designers
  • Analysts
  • Users

The default users and their assigned groups are:

  • Data Lake Administrator - Administrators, Users
  • Analyst - Analysts, Users
  • Designer - Designers, Users
  • Operator - Operations, Users

The initial installation will also have the auth-kylo and auth-file included in the active profiles configured in the conf/ file of both the UI and Services. With these profiles active the authentication process will use both the built-in Kylo user store and a username/password file to authenticate requests. In this configuration, all activated login modules will have to successfully authenticate a request before access will be granted.

Service-Level Authorization

At the service (functional) level, the actions available to be granted to a user or group are organized as follows:
