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

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

*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 '_'
