Hi,
Prior the installation HDF2.1 (HDF Management Pack) , we need to back up the Ambari resources, I'm wondering what is the purpose of this backup and how long we need to keep it?
Thanks,
SJ

Once you have successfully validated your HDF upgrade, you can get rid of your backup.
The backup of the Ambari resources was not always part of the procedure. It was added mainly because we found users were running a HDF upgrade on their HDP Ambari installs. By doing so they ended up messing up their HDP installs. HDF and HDP are two different product lines and the HDF mpack does not add to existing services, it makes available only those services in the HDF stack. So if you update the mpack on a HDP Ambari, you can really mess up your HDP cluster. So we added the steps to make a backup first.
So after upgrade and verifying that all services are accessible and running without error there is probably no reason to keep the backup much longer then that.
Thanks,
Matt
