Using the Restore Wizard to restore Hadoop data on the same Hadoop cluster

This topic describes how to use the Restore Wizard to restore Hadoop data on the same Hadoop cluster.

To use the Restore Wizard to perform a restore

  1. Open the Backup, Archive, and Restore interface.
  2. Select the appropriate date range to restore the complete data set.
  3. In the Browse directory, specify the root directory ( "/") as the path to browse.
  4. From the File menu (Windows) or Actions menu (UNIX), choose Specify NetBackup Machines and Policy Type.
  5. On the Specify NetBackup Machines and Policy Type wizard, enter the source and destination details for restore.
    • Specify the Hadoop NameNode as the source for which you want to perform the restore operation.

      From the Source client for restores list, select the required NameNode.

    • Specify the backup host as the destination client.

      From the Destination client for restores list, select the required backup host.

    • On the Specify NetBackup Machines and Policy Type wizard, enter the policy type details for restore.

      From the Policy type for restores list, choose BigData as the policy type for restore.

      Click Ok.

  6. Go to the Backup History and select the backup images that you want to restore.
  7. In the Directory Structure pane, expand the Directory.

    All the subsequent files and folders under the directory are displayed in the Contents of Selected Directory pane.

  8. In the Contents of Selected Directory pane, select the check box for the Hadoop files that you want to restore.
  9. Click Restore.
  10. In the Restore Marked Files dialog box, select the destination for restore as per your requirement.
    • Select Restore everything to its original location if you want to restore your files to the same location where you performed your backup.

    • Select Restore everything to a different location if you want to restore your files to a location which is not the same as your backup location.

  11. Click Start Restore.
  12. Verify the restored files.
