Export Data from SQL Server to HDFS through SSIS

Easily push SQL Server data to HDFS using the CData SSIS Tasks for HDFS.

SQL Server databases are commonly used to store enterprise records. It is often necessary to move this data to other locations. The CData SSIS Task for HDFS allows you to easily transfer HDFS data. In this article you will export data from SQL Server to HDFS.

Add Source and Destination Components

To get started, add a new ADO.NET Source control and a new HDFS Destination control to the data flow task.

Configure the ADO.NET Source

Follow the steps below to specify properties required to connect to the SQL Server instance.

  1. Open the ADO.NET Source and add a new connection. Enter your server and database information here.
  2. In the Data access mode menu, select "Table or view" and select the table or view to export into HDFS.
  3. Close the ADO NET Source wizard and connect it to the destination component.

Create a New Connection Manager for HDFS

Follow the steps below to set required connection properties in the Connection Manager.

  1. Create a new connection manager: In the Connection Manager window, right-click and then click New Connection. The Add SSIS Connection Manager dialog is displayed.
  2. Select CData HDFS Connection Manager in the menu.
  3. Configure the connection properties.

    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

Configure the HDFS Destination

In the destination component Connection Manager, define mappings from the SQL Server source table into the HDFS destination table and the action you want to perform on the HDFS data. In this article, you will insert Files entities to HDFS.

  1. Double-click the HDFS destination to open the destination component editor.
  2. In the Connection Managers tab, select the connection manager previously created.
  3. In the Use a Table, menu, select Files. In the Action menu, select Insert.
  4. On the Column Mappings tab, configure the mappings from the input columns to the destination columns.

Run the Project

You can now run the project. After the SSIS Task has finished executing, data from your SQL table will be exported to the chosen table.
