> *STR:*
> # On Nn ha environment, nn1 is on host1 and nn2 is on host2
> # Put host1 in maintenance mode
> # Start "Move namenode wizard"
> # Wizard will fail on last step "Delete disabled namenode+zkfc" because the
> namenode to be deleted which was in maintenace mode never stopped as part of
> wizard, and delete operation on a component in 'STARTED' state throws an
> exception
> # user ends up with 3 instances of namenode.
> It is reasonable to expect that the source host is in maintenance mode (the
> user is likely doing a move because the host is in bad state).
