Impersonation in MapR
Describes impersonation in MapR, which allows centralized control of access to resources in the MapR File System, MapR Database, and MapR Event Store For Apache Kafka.
Also known as identity assertion, impersonation is one user (authorized to impersonate
another) or the mapr
super user accessing data and submitting jobs on behalf
of another user. Implementing impersonation provides authoritative, end-to-end security for
your MapR installation,
independent of remote authentication and security mechanisms that control user access to
application features.
To implement impersonation in MapR, there are both MapR core and ecosystem component requirements that must be met as well as requirements at the application development level. These requirements are described in Access Control and Impersonation in MapR.
When all other requirements are met, enabling impersonation for the mapr superuser or for any other user is a simple task.
