             Summary: Create widget -> Add metric popup: UI tweaks
                 Key: AMBARI-10858
                 URL: https://issues.apache.org/jira/browse/AMBARI-10858
             Project: Ambari
          Issue Type: Task
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
             Fix For: 2.1.0
         Attachments: ScreenShot-1.png, ScreenShot-2.png, ScreenShot-3.png

Following needs to be achieved as part of this ticket:
# Select component dropdown: Slave component should be explicitly prefixed with *All*. Example: It should say "All DataNodes" instead of DataNode.
# Select component dropdown: Ambari metrics with Metric Collector component should not be shown as an option. Infact its metrics should not be asked from API.
# Select component dropdown: MapReduce2 service should not shown as an option. Infact its metrics should not be asked from API.
# Select component dropdown: YARN service should not show "All History server" and "Active History server"
# Select component dropdown: HBase service should not show "Active HBase master"
# When Add metric popup is launched it has metric dropdown with text "Select a metric" [^ScreenShot-1.png]. This automatically changes to the first filtered metric element in the list when a component is selected  but the "Add button" is not enabled [^ScreenShot-2.png]. Expected behavior is that "Select a metric" label should remain even when a component is selected and Add button should remain disabled. Once user selects a metric, Add button should be enabled.
# This is not related to Add metric popup but more to "Metrics and Expression" page. For Graph widget even when a label value is entered, metric is selected and valid expression is fixed by clicking "Done" button, Next button for the page remains disabled. [^ScreenShot-3.png]
