---------------------------------
Summary: Add Passive State for Service, Host, HostComponent
Key: AMBARI-4419
URL: https://issues.apache.org/jira/browse/AMBARI-4419
Project: Ambari
Issue Type: Task
Components: controller
Reporter: Nate Cole
Assignee: Nate Cole
Fix For: 1.5.0
Add ability set a new state on Service, Host, HostComponent - a Passive State.
Passive State is used to maintain control of a unit in Ambari, but skip
operations that include an item. Examples:
* If a Service is Passive, a call to restart all Services should skip a passive
one.
* However, said Service can be acted upon, if it is a direct target.
* A restart of a Service will ignore Hosts that are Passive.
* A restart of a Service will ignore HostComponents that are Passive.
* Rolling restarts do not affect items that are marked Passive
Passivated items will not generate alerts (that will be filed and tracked
separately)
