You can use the Apache Impala connector from the CData Sync application to capture data from Apache Impala and move it to any supported destination. To do so, you need to add the connector, authenticate to the connector, and complete your connection.

Add the Apache Impala Connector

To enable Sync to use data from Apache Impala, you first must add the connector, as follows:

1. Open the Connections page of the Sync dashboard.

2. Click Add Connection to open the Select Connectors page.

3. Click the Sources tab and locate the Apache Impala row.

4. Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the Apache Impala connector. For more information about installing new connectors, see Connections.

Complete Your Connection

     • HTTP - For this mode, you also must specify a value for HTTP Path, which is the path component of the URL endpoint. The default value is cliservice.
