Creating a Shared Data Context

Create a Shared Data Context to allow the Compute cluster to access data, metadata, and security services from the Base cluster. This shared context is required before you can create Compute clusters.

  • You have reviewed Cloudera Flow Management installation workflow and have decided to install NiFi on a Compute cluster.
  • You have prepared your Cloudera Base on premises Base cluster.
  • Your Base cluster has data, metadata, and security services to share.
  1. From Cloudera Manager Home, click on your Base cluster name to go the Detail page.
  2. In the Data Contexts section, click Create.
  3. In the Create Data Context dialog, provide a Data Context Name, specify your Base cluster, and click Create.

When you have finished creating a Shared Data Context, proceed to adding the NiFi and NiFi Registry groups to Ranger in the Base cluster if needed, then to creating a Compute cluster.
