Cloudbreak HDF cluster resizing

[#1]

Hi!

I'm wondered that resizing is not supported for HDF cluster in Cloudbreak. https://docs.hortonworks.com/HDPDocuments/Cloudbreak/Cloudbreak-2.9.0/manage-clusters/content/cb_res...

When I tried to add new NiFi instance via cloudbreak to my cluster, I couldn't access it. I got next error message in NiFi UI

Insufficient Permissions. Untrusted proxy CN=ip-10-157-32-237.ec2.internal, OU=NIFI

Do you have any idea how to fix it? And why Cloudbreak doesn't support resizing for HDF clusters?

Cloudbreak supports resizing HDF cluster but not those hostgroups which has NIFI service.
