Note: For HBase in a Custer with Ranger

If HBase is added in a cluster with Ranger, you must add an SSL certificate to allow HBase to communicate with ranger.

You must have these details in hand before performing the following task:
  • The IP address for the un0 or mn0 node, which can be retrieved either from the Console or the Apache Ambari.
  • The cluster name specified in Apache Ambari. To retrieve the cluster name, login to Apache Ambari. From the top toolbar, click the username dropdown menu and select Manage Ambari. The cluster name is displayed.
  • The cluster admin or Apache Ambari password you provided when you created the Big Data Service cluster.
  1. SSH to the first master node (mn0) of your ODH cluster node as opc user.
  2. If your cluster version is 3.0.7 or later, run the following command as the root user. 
    sudo bds_cert_util  --updateAmbariConfig

    You will be prompted for the Ambari password. Enter the Ambari password and wait for the tool to complete.

    For older versions of the cluster, run the following command as the root user.

    /home/opc/cloud/flask-microservice/cert_util/update_ranger_certs.sh <IP-address-for-un0-node> <cluster-name> <cluster-admin-ambari-password>
  3. Access Apache Ambari.
  4. Restart all the affected services. For cluster versions 3.0.6 or lower, the affected services are automatically restarted. Wait for all the services to be restarted.
  5. From the side toolbar, under Services click HBase.
  6. From the Actions menu, click Run Service Check. A successful service check ensures that HBase is installed properly.
