Update HDFS Data with a Microsoft Access Linked Table

Update HDFS data by creating a linked table in Microsoft Access with the CData HDFS ODBC Driver.

CData ODBC drivers connect your data to any database management tool that supports Open Database Connectivity (ODBC). This includes many of the most popular productivity tools, adding new capabilities for document sharing and collaboration. Using the CData ODBC driver for HDFS, you can update live HDFS data in Microsoft Access; for example, you can make updates that can be immediately seen by other users.

Connect to HDFS as an ODBC Data Source

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

Create a Linked Table to Files Data

Follow the steps below to create a linked table, which enables you to access live Files data.

  1. On the External Data tab in Access, click ODBC Database.
  2. Select the option to link to the data source. A linked table will enable you to read from and write data to the Files table.
  3. Select the CData HDFS data source from the Machine Data Source tab.

  4. Select the Files table. For more information on this table, see the "Data Model" chapter in the help documentation.
  5. Double-click the linked table to make edits. The linked table will always have up-to-date data and any changes will be reflected back to the underlying table.
