Backing up and Restoring Profiler Database
Using certain scripts that can be executed by the
root users, you
can take the backup of the Profiler databases. Later, if you want to delete the existing
DataHub cluster and launch a new DataHub cluster, you must have an option to restore the old
Data Catalog includes Profiler services that run data profiling operations on data that is located in multiple Data Lakes. As of the latest Cloudera Runtime release, the Profiler services run on a DataHub cluster. When you delete the DataHub cluster, the profiled data and the user configuration information stored in the local databases are lost.
Profiler clusters run on the DataHub cluster using a couple of embedded databases - profiler_agent and profiler_metrics.
