------------------------------

             Summary: Make Host bulk command menu item list stack driven instead of a hardcoded
list in UI code
                 Key: AMBARI-15443
                 URL: https://issues.apache.org/jira/browse/AMBARI-15443
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server, ambari-web
    Affects Versions: trunk
            Reporter: Di Li
            Assignee: Di Li
             Fix For: trunk


The items described here are the ones on the Hosts tab, in the Actions drop-down list where
the UI shows entries such as All Hosts. If user mouses over the All Hosts, it shows a sub-list
including Hosts and slave components. 

The slave component items are hardcoded in hosts_table_menu_view.js as shown below. This jira
is to put this info into each service's metainfo.xml so that the slave component items can
be stack driven.

components: function () {
    var serviceNames = App.Service.find().mapProperty('serviceName');
var menuItems = [
      O.create({
        serviceName: 'HDFS',
        componentName: 'DATANODE',
        masterComponentName: 'NAMENODE',
        componentNameFormatted: Em.I18n.t('dashboard.services.hdfs.datanodes')
      }),
      O.create({
        serviceName: 'YARN',
        componentName: 'NODEMANAGER',
        masterComponentName: 'RESOURCEMANAGER',
        componentNameFormatted: Em.I18n.t('dashboard.services.yarn.nodeManagers')
      }),
      O.create({
        serviceName: 'HBASE',
        componentName: 'HBASE_REGIONSERVER',
        masterComponentName: 'HBASE_MASTER',
        componentNameFormatted: Em.I18n.t('dashboard.services.hbase.regionServers')
      }),
      O.create({
        serviceName: 'STORM',
        componentName: 'SUPERVISOR',
        masterComponentName: 'SUPERVISOR',
        componentNameFormatted: Em.I18n.t('dashboard.services.storm.supervisors')
      })];

    return menuItems.filter(function (item) {
      return serviceNames.contains(item.serviceName);
    });
  }.property(),
