Do we have a way to use Cloudbreak for installing HDP cluster on bare metal servers? I know Cloudbreak works with AWS/GCP/Azure and OpenStack but I would like to know if Cloudbreak can spin-off clusters either by using Docker or directly on on-premise physical nodes with out OpenStack managing the hardware . please advise

@Divakar Annapureddy Does this mean that we can't restore the cluster with the meta-data/data backups we take before the cluster re-install?

What is the best approach to restore HDP cluster if a customer would like to migrate from SUSE OS on an existing HDP cluster to RHEL OS? Is it same as re-installing OS/HDP cluster and restoring it with the backup data/config? please advise.

@jramakrishnan This looks more like authentication solution than securing the data channels to eliminate the risk of having your data transfer in clear text. Am i missing anything here?

Is there any way to secure the data transfer between the source and datanodes while using Sqoop? I know we can use Kerberos for authentication but not sure if we have any way to secure the data transfer. Please advise.

We enabled Yarn Resource Manager HA on our cluster ( HDP 2.3.2 and Ambari 2.1.2.1) and it was working fine until we re-installedRanger KMS server from the cluster. When the ResrouceManager HA was working, I saw one of them as active Resource Manager and the other one as Stand-by but they both are now showing as ResourceManager and also when I run the service check on yarn .. it is failing with the following error message Traceback (most recent call last):
File "/var/lib/ambari-agent/cache/common-services/YARN/2.1.0.2.0/package/scripts/service_check.py", line 142, in <module>

I am new to TDE and one of our customers would like to know the following: What happens when an encrypted file is moved from encrypted zone to another location on HDFS? can we still decrypt and re-encrypt that file using the same key? or we can't decrypt that file once it is moved from its encrypted zone location.
