What is the definitive way of backing up and restoring HDFS Metadata in NameNode HA environment on Ambari + HDP?

(Note: I use Ambari 2.6.2.2 + HDP 2.6.5 for now.)

I read this article https://www.cloudera.com/documentation/enterprise/5-8-x/topics/cm_mc_hdfs_metadata_backup.html (sorry, this is Cloudera's), but this article uses Cloudera Manager for restoring.

You can follow the article given at https://community.hortonworks.com/content/supportkb/151074/how-to-perform-hdfs-metadata-backup-and-f...

Ambari does not provide any option for backup in this case.
