(v7) Manage the Cloudera Search Connector

Manage the Cloudera Search Connector

Composer supports Cloudera Search version 4.10 - 7.4.

Before you can establish a connection from Composer to Cloudera Search storage, a connector server needs to be installed and configured. See Manage Connectors and Connector Servers for general instructions and Connect to Cloudera Search for details specific to the Cloudera Search connector.

After the connector has been set up, you can create data source configurations that specify the necessary connection information and identify the data you want to use. See Manage Data Source Configurations for more information. After data sources are configured, they can be used to create dashboards and visuals from your data. See Create Dashboards.
