> Ambari API has implemented operator precedence for predicates.
> Previously, a=1|a=2|a=3&b=1 was interpreted as (a==1||a==2||a==3)&&(b==1).
> With the addition of operator precedence, it would be interpreted as a==1||a==2||(a==3&&b==1).
> In step9_controller, UI makes a call to App.apiPrefix + '/clusters/' + clusterName + '/host_components?HostRoles/component_name=GANGLIA_MONITOR|HostRoles/component_name=HBASE_REGIONSERVER|HostRoles/component_name=DATANODE|HostRoles/component_name=TASKTRACKER&HostRoles/state=INSTALLED'.
> This is for starting service components that have been installed during Add Host Wizard.
> This should be changed to App.apiPrefix + '/clusters/' + clusterName + '/host_components?(HostRoles/component_name=GANGLIA_MONITOR|HostRoles/component_name=HBASE_REGIONSERVER|HostRoles/component_name=DATANODE|HostRoles/component_name=TASKTRACKER)&HostRoles/state=INSTALLED'.
