> Ambari is creating unlimited widget dashboards in database if user name
> contains '_' and none of them is returned when call :
> http://<AMBARI_SERVER>:8080/api/v1/users/USER_NAME/activeWidgetLayouts
> *Reproduction steps*
> Create a User with underscore in ambari , for ex : Test_User
> assign cluster user permissions to created user.
> Login as Test_User
> Navigate to Services >> Yarn
> Click on Plus icon on UI .
> Try to 'Add' any of widgets.
> When try to add any widgets in dashboard there exists a script error refer to
> Screen Shot 2018-05-28 at 6.22.35 PM.png
> Additionally ambari-web client keeps sending the Request to create new widget
> layout in recursive mode which results in infinite number of duplicate
> entries in database in widget_layout database and user_Widget_layout
> database. refer to Screen Shot 2018-05-28 at 6.22.25 PM.png
> *root cause :*
> Ambari-server saves the dashboard layouts in database by name
> "USER_SERVICENAME_DASHBOARD" and somewhere parsing logic is going wrong as
> username contains '_'
