Hello Team, I am new to CDP. I need to change the NameNode to a different host and also need to change the Balancer to a different host and CREATE a journal node and change role of various other hosts. I created "HOST TEMPLATES" in accordance to my requirement and "STOPPED THE ROLES". Now, while i am trying to import the "Host Template", I get the below error. Any help is appreciated.

But I have stopped the roles on that host. Yet I receive the same error.
