Connect to HDFS Data in DBArtisan

The CData ODBC Driver for HDFS seamlessly integrates HDFS data into database management tools like DBArtisan by enabling you to access HDFS data as a database. This article shows how to create an data source for HDFS in DBArtisan and execute queries. You can then edit data visually and execute standard SQL.

Integrate HDFS Data into DBArtisan Projects

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

In order to authenticate, set the following connection properties:

• Host: Set this value to the host of your HDFS installation.
• Port: Set this value to the port of your HDFS installation. Default port: 50070

You can then follow the steps below to register HDFS data as a database instance in your project:

1. In DBArtisan, click Data Source -> Register Datasource.
2. Select Generic ODBC.
3. Enter a name for the data source and select the DSN.
4. Finish the wizard to connect to HDFS data. HDFS entities are displayed in the Datasource Explorer.

You can now work with HDFS data as you work with any other database. See the driver help documentation for more information on the queries supported by the HDFS API.
