Creating trace user in unsecure Operational Database powered by Apache Accumulo deployment
After you add an unsecure Accumulo on CDP service, you have to ensure that the trace user exists. This step is only required if you have an unsecure Operational Database powered by Apache Accumulo (OpDB) deployment.
This step is not required if you have a secure OpDB deployment, because in that case the trace user is automatically created when the Accumulo on CDP service is added to the cluster.
- Install the OpDB CSD file.
- Install CDP and add the HDFS and ZooKeeper services to your deployment.
- Install the OpDB parcel.
- Add an unsecure Accumulo on CDP to your deployment.
