> Project: Ambari
> Issue Type: Task
> Components: ambari-web
> Affects Versions: 1.7.0
> Reporter: Andrii Tkach
> Assignee: Andrii Tkach
> Priority: Critical
> Fix For: 1.7.0

>
> Host details page allows adding any uninstalled client component and some
> non-client component to the host.
> But there are some components that have a host scope dependencies on another
> components. For example, Slider client won't function properly if HDFS client
> and YARN client are not installed with it on the same host and thus slider
> client has host scope dependencies on HDFS and YARN client. Such information
> is available from API.
> As a part of this ticket, ambari-web should maintain a map of host scope
> dependencies for every component in StackServiceComponent model.
> On host page while adding a component, ambari-web code should check if the
> component's host scope dependencies are installed or not on that host. If not
> then show a single button ("OK") popup window informing the user to install
> them first:
> *popup window message:*
> {code}"${ComponentNameTobeAdded} requires ${componentName},${componentName}
> and ${componentName} to be installed along with it. Please add them first and
> then try adding ${{ComponentNameTobeAdded}"{code}
