Restore Hadoop data on the same Hadoop cluster

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

To restore Hadoop data on the same Hadoop cluster

  1. Open the web UI.
  2. On the left, select Recovery.
  3. On the Regular recovery card, click Start recovery.
  4. On the Basic properties tab, enter the following:
    • For the Policy type select BigData > Hadoop.

    • Specify the Hadoop application server as the source for which you want to perform the restore operation.

      From the Source client list, select the required Application server.

    • Specify the backup host as the destination client.

      From the Destination client list, select the required backup host. Restore is faster if the backup host is the media server that had backed up the node.

    • Click Next.

  5. On the Recovery details tab, do the following:
    • Select the appropriate date range to restore the complete data set or go to Use backup history and select the backup images that you want to restore.

    • From left directory hierarchy, select the files and folders for restore.

      Note:

      All the subsequent files and folders under the directory are displayed in the right pane.

    • Click Next.

  6. On the Recovery options tab, do the following:
    • Select Restore everything to 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.

      Provide the path.

    • Select Restore individual directories and files to different locations if you want to restore files and directories to separate locations.

      Edit and add file path.

    • In Recovery options, select the appropriate options.

    • Click Next.

  7. On the Review tab, verify the details and click Start recovery.
