Best practices for restoring a Hadoop cluster

When restoring a Hadoop cluster, consider the following points:

  • Before you run a restore job, ensure that there is sufficient space on the cluster to complete the restore job.

  • Update the firewall settings so that the backup hosts can communicate with the NetBackup for Hadoop cluster.

  • Ensure that you have the valid certificates all the cluster nodes for a Hadoop cluster that is enabled with SSL (HTTPS).

  • Ensure that you have the valid PEM certificate file on the backup host.

  • Ensure that correct parameters are added in the hadoop.conf file for HTTP or HTTPS-based clusters.

  • Ensure that the backup host contains a valid CRL that is not expired.

  • Application-level or file system-level encryption is not supported for Hadoop. You must be a Hadoop superuser to ensure that the restore works correctly.
