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.

    2. Click the Components tab.
    3. Choose HBase > Service Configuration, and set Type to All.
    4. Search for hbase.security.authorization and change its value to true (select the first HBase parameter).

    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.

    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

      Figure 6 Adding an access control policy
    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 permission 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
