Bugs: AMBARI-14614
    https://issues.apache.org/jira/browse/AMBARI-14614


Repository: ambari


Description
-------

Hosts which are in maintenance mode are still included in the list of candidate hosts for
service checks when checking a client-only service such as Tez or Slider.

- Install a cluster with at least 2 hosts which have a client-only service like Tez or Slider
- Place 1 of 2  client-only service hosts into maintenance mode 
- Upgrade

The orchestration will have a used the host in maintenance mode for service checks for the
client-only service.
