Description

Patch upgrade is going into incorrect state when invalid VDF is used during package installation.
Steps to reproduce :
1) Create a Centos7 HDP cluster with ambari
2) Register the VDF for Centos6 (mistakenly I registered the invalid VDF)
3) Click on install packages.
Install packages throws 500 ("Repositories for os type redhat7 are not defined. Repo version=2.6.0.2-81, stackId=HDP-2.6"), but in the UI it still shows the state as 'installing'. Also Its not allowing to deregister the VDF as the state is installing.
Its better to check the validity of the VDF during registration, rather than failing during package installation.
Workaround : I was able to come out of this state by restarting ambari server and I was able to deregister the version as well.
