Binding Tenant to an MRS Cluster User

Scenario

A newly created tenant cannot directly log in to the cluster to access resources. You need to add a user for the tenant on FusionInsight Manager and bind the user to the role of the tenant to assign operation permissions to the user.

Prerequisites

You have clarified service requirements and created a tenant.

Procedure

If you want to add a user to the system, click Create.

Figure 1 Adding a user

If you want to bind tenant roles to an existing user in the system, locate the row of the user and click Modify in the Operation column.

Set user attributes according to Table 1.

**Table 1** User parameters
Parameter	Description
Username	Indicates the current username. The value contains 3 to 32 characters, including digits, letters, underscores (_), hyphens (-), and spaces. The username cannot be the same as the OS username of any node in the cluster. Otherwise, the user cannot be used. A username that differs only in alphabetic case from an existing username is not allowed. For example, if User1 has been created, you cannot create user1. Enter the correct username when using User1.
User Type	The options are Human-Machine and Machine-Machine. Human-Machine user: used for FusionInsight Manager O&M and component client operations. If you select this option, set both Password and Confirm Password accordingly. Machine-Machine user: used for application development. If you select this option, the password is randomly generated.
Password	This parameter is mandatory if User Type is set to Human-Machine. The password must contain 8 to 64 characters of at least four types of the following: uppercase letters, lowercase letters, digits, special characters, and spaces. The password cannot be the username or the username spelled backwards.
Confirm Password	Enter the password again.
User Group	In the User Group area, click Add and select user groups to add the user to the groups. If roles have been added to the user groups, the user can be granted the permissions of the roles. For example, add the user to the Hive user group to assign Hive permissions to the user.
Primary Group	Select a group as the primary group for the user to create directories and files. The drop-down list contains all groups selected in User Group.
Role	Click Add to bind a tenant role to the user. NOTE: If a user wants to use the resources of tenant tenant1 and to add or delete sub-tenants for tenant1, the user must be bound to both the Manager_tenant and tenant1_Cluster ID roles. If the tenant has been associated with the HBase service and Ranger authentication is enabled for the cluster, you need to configure the HBase execution permissions on the Ranger page.
Description	Indicates the description of the current user.
