Configuring HBase Access Permissions in Ranger

After an MRS cluster with Ranger installed is created, HBase access control is not integrated into Ranger. This section describes how to integrate HBase into Ranger.

1. Log in to the Ranger web UI.
2. In the Service Manager area, click next to HBASE to add an HBase service.
   Figure 1 Adding an HBase service
   

3. Set the parameters for adding an HBase service according to Table 1. Use the default values for the parameters that are not listed in the table.

   Table 1 Parameter description

   Parameter	Description	Example Value
   Service Name	Name of the service to be created. The value is fixed to hbasedev.	hbasedev
   Username	You can set this parameter to any value.	admin
   Password	You can set this parameter to any value.	-
   hadoop.security.authentication	Hadoop authentication mode. The value is fixed to Simple.	Simple
   hbase.security.authentication	HBase authentication mode. The value is fixed to Simple.	Simple
   hbase.zookeeper.property.clientPort	Port number of ZooKeeper in the HBase cluster.	2181
   hbase.zookeeper.quorum	ZooKeeper address in the HBase cluster.	192.168.0.7,192.168.0.8,192.168.0.9
   zookeeper.znode.parent	Path of the root node of HBase in ZooKeeper. The value is fixed to /hbase.	/hbase

4. Click Add to add the service.
5. Start the Ranger HBase plugin to authorize Ranger to manage HBase.
   1. On the MRS management console, click the cluster name to go to the cluster details page.
   2. Click the Components tab.
   3. Choose HBase > Service Configuration and switch Basic to All.
   4. Search for hbase.security.authorization and change its value to true (select the first HBase parameter).
      Figure 3 Modifying hbase.security.authorization
      
   5. Search for hbase.coprocessor.master.classes and append ,org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor to its original value.
      Figure 4 hbase.coprocessor.master.classes
      
   6. Search for hbase.coprocessor.region.classes and append ,org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor to its original value.
      Figure 5 hbase.coprocessor.region.classes
      
   7. Click Save Configuration and select Restart the affected services or instances to restart the HMaster and RegionServer instances.

6. Create a policy under HBase Service hbasedev.
   1. Log in to the Ranger web UI.
   2. In the HBASE area, click the added service hbasedev.
   3. Click Add New Policy to add an access control policy.
   4. Set the parameters according to Table 2. Use the default values for the parameters that are not listed in the table.

      Table 2 Parameter description

      Parameter	Description	Example Value
      Policy Name	Policy name	Policy002
      HBase Table	Name of the HBase table that the policy allows to access	test1
      HBase Column-family	Column family of the HBase table that the policy allows to access	cf1
      HBase Column	Column name of the table corresponding to the HBase table that the policy allows to access	name
      Allow Conditions	Select Group: user group that the policy allows to access Select User: user in the user group that the policy allows to access Permissions: permissions that the policy allows the user to have	Select Group: testuser Select User: testuser Permissions: Create and Select

   5. Click Add to add the policy. According to the preceding policy, user testuser in the testuser user group has the Create and Select permissions on the cf1:name column in the test1 table of the default namespace in HBase, but no permissions to access other columns.

7. Update and log in to the HBase client by referring to Using HBase from Scratch, and check whether HBase has been integrated into Ranger.
   1. Run the following command to access the HBase shell:

      source /opt/client/bigdata_env

      hbase shell

      Figure 7 Accessing the HBase shell
      
   2. Add data and check whether Ranger is integrated.
      1. Add data to the cf1:name column in the test1 table.

         put 'test1','001','cf1:name','tom'

      2. Add data to the cf1:age column in the test1 table. If the user has no permission to access this column, the data fails to be added.

         put 'test1','001','cf1:age',10
