Adding a Ranger Access Permission Policy for HBase

Scenario

Ranger administrators can use Ranger to configure permissions on HBase tables, column families, and columns for HBase users.

Prerequisites

• The Ranger service has been installed and is running properly.
• You have created users, user groups, or roles for which you want to configure permissions.

Procedure

1. Log in to the Ranger web UI as the Ranger administrator rangeradmin. For details, see Logging In to the Ranger Web UI.
2. On the home page, click the component plug-in name in the HBASE area, for example, HBase.
3. Click Add New Policy to add an HBase permission control policy.
4. Configure the parameters listed in the table below based on the service demands.

   Table 1 HBase permission parameters

   Parameter	Description
   Policy Name	Policy name, which can be customized and must be unique in the service.
   Policy Conditions	IP address filtering policy, which can be customized. You can enter one or more IP addresses or IP address segments. The IP address can contain the wildcard character (*), for example, 192.168.1.10,192.168.1.20, or 192.168.1.*.
   Policy Label	A label specified for the current policy. You can search for reports and filter policies based on labels.
   HBase Table	Name of a table to which the policy applies. The value can contain wildcard (*). For example, table1:* indicates all tables in table1. The Include policy applies to the current input object, and the Exclude policy applies to objects other than the current input object. NOTE: The value of hbase.rpc.protection of the HBase service plug-in on Ranger must be the same as that of hbase.rpc.protection on the HBase server. For details, see When an HBase Policy Is Added or Modified on Ranger, Wildcard Characters Cannot Be Used to Search for Existing HBase Tables.
   HBase Column-family	Name of the column families to which the policy applies. The Include policy applies to the current input object, and the Exclude policy applies to objects other than the current input object.
   HBase Column	Name of the column to which the policy applies. The Include policy applies to the current input object, and the Exclude policy applies to objects other than the current input object.
   Description	Policy description.
   Audit Logging	Whether to audit the policy.
   Allow Conditions	Policy allowed condition. You can configure permissions and exceptions allowed by the policy. In the Select Role, Select Group, and Select User columns, select the role, user group, or user to which the permission is to be granted, click Add Conditions, add the IP address range to which the policy applies, and click Add Permissions to add the corresponding permission. Read: permission to read data Write: permission to write data Create: permission to create data Admin: permission to manage data Select/Deselect All: Select or deselect all. If users or user groups in the current condition need to manage this policy, select Delegate Admin. These users or user groups will become the agent administrators. The agent administrators can update and delete this policy and create sub-policies based on the original policy. To add multiple permission control rules, click . To delete a permission control rule, click . Exclude from Allow Conditions: policy exception conditions
   Deny All Other Accesses	Whether to reject all other access requests. True: All other access requests are rejected. False: Deny Conditions can be configured.
   Deny Conditions	Policy rejection condition, which is used to configure the permissions and exceptions to be denied in the policy. The configuration method is similar to that of Allow Conditions. The priority of Deny Conditions is higher than that of allowed conditions configured in Allow Conditions. Exclude from Deny Conditions: exception rules excluded from the denied conditions
