Changing the Hadoop Version on Windows

Changing the Hadoop Version on Windows

You can configure B2B Data Exchange on the Windows operating system to connect to a different HDFS version.
  1. Shut down the B2B Data Exchange service and close the Operation Console.
  2. Open
    <DXInstallationDir>\bin\dxhadoop.bat
     in a text editor.
    The file displays a list of commands to connect to a specific HDFS version. The line that contains the version to which B2B Data Exchange connects appears in the following format: 
    set DX_HADOOP_CLASS_PATH=%DX_HOME%\hadoop\<selected version>\lib\*
    The other supported HDFS versions appear in the following format: 
    :: set DX_HADOOP_CLASS_PATH=%DX_HOME%\hadoop\<supported version>\lib\*
  3. To instruct B2B Data Exchange to connect to a different HDFS version, remove the two colon (
    ::
    ) comment indicator at the beginning of the line that contains the HDFS version to which you want B2B Data Exchange to connect.
  4. Add two colons (
    ::
    ) as comment indicators at the beginning of the line that contains the HDFS version to which you no longer want B2B Data Exchange to connect.
    If you select more than one HDFS version, the connection may fail.
  5. Open
    <DXInstallationDir>\conf\wrapper.hadoop.conf
     in a text editor.
    The file displays a list of commands to connect to a specific HDFS version. The line that contains the version to which B2B Data Exchange connects appears in the following format: 
    wrapper.java.classpath.6=./hadoop/<selected version>/lib/*.jar
    The other supported HDFS versions appear in the following format: 
    # wrapper.java.classpath.6=./hadoop/<supported version>/lib/*.jar
  6. To instruct B2B Data Exchange to connect to a different HDFS version, remove the number sign (
    #
    ) comment indicator at the beginning of the line that contains the HDFS version to which you want B2B Data Exchange to connect.
    The HDFS versions that you define in the
    wrapper.hadoop.conf
     file and the
    dxhadoop.bat
     file must be identical.
  7. Add a number sign (
    #
    ) as a comment indicator at the beginning of the line that contains the HDFS version to which you no longer want B2B Data Exchange to connect.
    If you select more than one HDFS version, the connection may fail.
  8. Save and close the
    wrapper.hadoop.conf
     file and the
    dxhadoop.bat
     file.
  9. Restart the B2B Data Exchange service and open the Operation Console.
