Duplicate a Hadoop cluster connection

You can duplicate a cluster connection. This task is useful if you want to test a change to a named connection without affecting the existing setup or if you want to add different security permissions.

To duplicate a cluster connection, perform the following steps:

1. Click the Hadoop clusters folder in the View tab.

2. Right-click an existing connection and select Duplicate cluster.

   The Hadoop clusters (Edit cluster) dialog box appears.

3. Enter a different name in the Cluster Name field.

   The system automatically adds copy-of- to the beginning of the cluster name.

4. Click Browse to add files(s). Use the file browser to select the site.xml files you want to import.

   Note: Duplicating a cluster connection copies the existing site.xml files to a new metastore directory. If you select site.xml files in this step, these files replace the copied site.xml.

5. Click Next.

6. For the security type, select None and click Next or see Add security to cluster connections to add or edit security.

7. Click Edit cluster to open the Edit cluster dialog box

8. Make the applicable changes to the cluster configuration values, then click Next.

   The Congratulations dialog box appears.

9. Click Close.
