Setup Guide

Follow these steps to connect Apache Impala to your CData Connect Cloud account:

  1. Open the Connections page of the CData Connect Cloud dashboard.

  2. Click + Add Connection in the upper-right corner.

  3. Type Apache Impala into the search field, then click the data source name.

  4. On the Basic Settings tab of the new connection, enter a connection name or keep the default name.

  5. Select a Transport Mode of BINARY or HTTP.

  6. Enter the following information:

    • HTTP Path—(HTTP transport mode only) the path component of the URL endpoint. The default value is “cliservice”.

    • User—the Apache Impala username for authentication.

    • Password—the user password.

    • Port—the port for connecting to the Apache Impala server. For HTTP transport mode, this should be set to the value of the ‘hs2_http_port’ property of the Impala configuration (default: 28000).

    • Server—the name or network address of the SQL Server instance.

    • Database—(optional) the name of the Impala database to connect to. If not specified, the default database schema is used.

  7. At the top of the CData Connect Cloud Add Apache Impala Connection page, click Save & Test.

    • If the connection test succeeds, a message indicates that your connection has been created. The Status on the Edit Connection page also changes to Authenticated.

    • If the connection test fails, ensure that you entered your login information correctly with no stray spaces or other characters. CData Connect Cloud displays error messages under the required fields with missing data. Some data sources require that you sign in directly to the source website. If you did not, an error message appears under the Sign in button. Correct the errors and try again.
