When an HBase Policy Is Added or Modified on Ranger, Wildcard Characters Cannot Be Used to Search for Existing HBase Tables

Question

When a Ranger access permission policy is added for HBase and wildcard characters are used to search for an existing HBase table in the policy, the table cannot be found. The following error is reported in /var/log/Bigdata/ranger/rangeradmin/ranger-admin-*log:

Answer

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.

  1. Log in to the Ranger management page. For details, see Logging In to the Ranger Web UI.
  2. In the HBASE area on the home page, click the component plug-in name, for example, the button of HBase.
  3. Search for the configuration item hbase.rpc.protection and change its value to the value of hbase.rpc.protection on the HBase server.
  4. Click Save.
