Xi Wang commented on AMBARI-3064:
---------------------------------
patch_3 added. In this patch, there is a newly add 'checkServicesChange' method which will
check added/deleted services, then adjust the widgets to show. This works for: after ambari
upgraded OR added/deleted services, the same user login, the dashboard would show correct
widgets.
> Ambari UI widgets should tolerate addition or removal of services

> When Ambari was upgraded from 1.2.5.17 to 1.4.0.18, MAPRDEDUCE was removed and YARN and
MAPREDUCE2 were added.
> The persist value of widgets still had the widgets for MAPREDUCE due to which the dashboard
came up to empty.
> So, we need to update the persist value for the same user if stack has upgraded.
