Akhil S Naik updated AMBARI-23961:
----------------------------------
Description:
Update: This was originally reported as Ambari is creating unlimited widget
dashboards in database if user name contains '_'. Upon further analysis, it
turns out that this happens if the username contains at least one uppercase
letter. Underscores do not matter. The dashboard works fine for a user name
like first_last.
###
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 '_'
Impact
We are not able to see any of dashboards and each time when customer login and
navigate to service there exists lots of REST calls to server results in
increased network calls and increased DB size.
