Export Data from SQL Server to Hive through SSIS

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

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 Hive allows you to easily transfer Hive data. In this article you will export data from SQL Server to Hive.

Add Source and Destination Components

To get started, add a new ADO.NET Source control and a new Hive 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 Hive.
  3. Close the ADO NET Source wizard and connect it to the destination component.

Create a New Connection Manager for Hive

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 ApacheHive Connection Manager in the menu.
  3. Configure the connection properties. A typical connection requires:
    • Server
    • Port
    • TransportMode

    Apache Hive への接続を確立するには以下を指定します。

    • Server:HiveServer2 をホストするサーバーのホスト名またはIP アドレスに設定。
    • Port:HiveServer2 インスタンスへの接続用のポートに設定。
    • TransportMode:Hive サーバーとの通信に使用するトランスポートモード。有効な入力値は、BINARY およびHTTP です。デフォルトではBINARY が選択されます。
    • AuthScheme:使用される認証スキーム。有効な入力値はPLAIN、LDAP、NOSASL、およびKERBEROS です。デフォルトではPLAIN が選択されます。
    • 本製品においてTLS/SSL を有効化するには、UseSSL をTrue に設定します

Configure the Hive Destination

In the destination component Connection Manager, define mappings from the SQL Server source table into the Hive destination table.

  1. Double-click the Hive destination to open the destination component editor.
  2. In the Connection Managers tab, select the connection manager previously created.
  • Specify the table into which the data will be exported: On the Component Properties tab, enter the table name in the TableName property, under the Custom Properties section. In this case, you will transfer Customers records.
  • 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.
