> Project: Ambari
> Issue Type: Improvement

> Fix For: 0.9.0

> Attachments: AMBARI-574.patch

>
> Currently, Step 6 of the Cluster Install Wizard is one massive form that
> shows all parameters for all services (and takes up multiple screens worth of
> vertical space).
> This is disorienting and not very user-friendly.
> There is a number of improvements that can be made for this page:
> * Create a tab for each service and organize configuration parameters within
> the tabbed content
> * Be explicit about the fields that are required but do not have any default
> content
> * Show Nagios and Hive configurations first, as they contain fields that are
> required but don't have default content
> * Always require the user to enter passwords (currently, Nagios Admin
> password is pre-filled but they are showing as *** so this is confusing)
> * Do not let the user submit the form if there are any client-side
> validation errors that have not been addressed (toggle the submit button
> enabled/disabled state based on the number of client-side validation errors).
> * Upon submission and server-side validation error, show the number of
> validation errors for each service inside the corresponding tab
> * As the user make corrections, clear the field error messages (for example,
> when we show the field error that the field is required, but we don't clear
> the error message after the user fills the field).
> * Dynamically change the number of errors per service in the tab as
> client-side validation errors are generated/cleared.
