Creating a Kafka Role

Create and configure a Kafka role as an MRS cluster administrator.

This section applies to MRS 3.x or later.

Users can create Kafka roles only in security mode.

If the current component uses Ranger for permission control, you need to configure permission management policies based on Ranger. For details, see Adding a Ranger Access Permission Policy for Kafka.

The MRS cluster administrator has understood service requirements.

Log in to FusionInsight Manager and choose System > Permission > Role.
On the displayed page, click Create Role and enter a Role Name and Description.
On the Configure Resource Permission page, choose Name of the desired cluster > Kafka.

Select permissions based on service requirements. For details about configuration items, see Table 1.
