RapidMiner からHBase Data にデータ連携

RapidMiner Studio の標準コンポーネントおよびデータソース設定ウィザードでHBase data を連携します。

この記事では、CData JDBC driver for HBase をRapidMiner のプロセスに簡単に統合する方法を説明します。ここでは、HBase にCData JDBC ドライバーを使用して、HBase data をRapidMiner のプロセスに転送します。

JDBC データソースとしてRapidMiner のHBase に接続

You can follow the procedure below to establish a JDBC connection to HBase:

  1. Add a new database driver for HBase:Click Connections -> Manage Database Drivers.
  2. In the resulting wizard, click the Add button and enter a name for the connection.
  3. Enter the prefix for the JDBC URL: jdbc:apachehbase:
  4. Enter the path to the cdata.jdbc.apachehbase.jar file, located in the lib subfolder of the installation directory.
  5. Enter the driver class: cdata.jdbc.apachehbase.ApacheHBaseDriver
  6. Create a new HBase connection:Click Connections -> Manage Database Connections.
  7. Enter a name for your connection.
  8. For Database System, select the HBase driver you configured previously.
  9. Enter your connection string in the Host box.

    Set the Port and Server to connect to Apache HBase.

    For assistance in constructing the JDBC URL, use the connection string designer built into the HBase JDBC Driver.Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.apachehbase.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    A typical connection string is below:

    Server=127.0.0.1;Port=8080;
  10. Enter your username and password if necessary.

You can now use your HBase connection with the various RapidMiner operators in your process.To retrieve HBase data, drag the Retrieve operator from the Operators view. With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry."In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the HBase data.
