Examples of HostRoleCommand

org.apache.ambari.server.actionmanager.HostRoleCommand
This class encapsulates the information for an task on a host for a particular role which action manager needs. It doesn't capture actual command and parameters, but just the stuff enough for action manager to track the request. For the actual command refer {@link HostAction#commandToHost}
