Add unsecure Accumulo on CDP service to your cluster

If your cluster is not an SASL enabled Kerberized cluster, add an unsecure Accumulo on CDP service to your cluster when installing Operational Database powered by Apache Accumulo (OpDB).

  • Install OpDB CSD file.
  • Install CDP and add the HDFS and ZooKeeper services to your deployment.
  • Install the OpDB parcel.
  1. Navigate to the Cloudera Manager Admin Console home page.
  2. Click the action menu of the cluster to which you want to add the Accumulo on CDP service (for example, Cluster 1), and select Add Service.
  3. Select Accumulo on CDP and click Continue.
  4. Select the dependent services and click Continue.
  5. Assign the Accumulo roles to the hosts in your cluster:
    • Assign a Table Server role on each host to which the DataNode role is assigned.
    • Assign the Monitor, Garbage Collector, Tracer, and Master role to non-DataNodes.
    • Assign the Gateway role to any hosts where you want to use the Accumulo on CDP service, and where you do not already have any other OpDB roles assigned.
  6. Click Continue.
  7. Configure the Accumulo Instance Secret.
  8. Set the Accumulo Instance Name.
  9. Set the Trace User and Trace Password settings.
    It is recommended that you not leave the Trace User set to root, because this is not a secure configuration.
  10. If this is the first installation of OpDB, ensure that the Initial Accumulo option is selected.
  11. Click Continue.
  12. Wait while Cloudera Manager does the initial service setup.
  13. Click Continue.
  14. Click Finish.
Ensure that the trace user and trace table exist.
