------------------------------------------
Summary: Give user visual feedback while we do background request
and next button is disabled
Key: AMBARI-16432
URL: https://issues.apache.org/jira/browse/AMBARI-16432
Project: Ambari
Issue Type: Task
Components: ambari-web
Affects Versions: 2.4.0
Reporter: Oleg Nechiporenko
Assignee: Oleg Nechiporenko
Priority: Critical
Fix For: 2.4.0
User may think that he is blocked or did something wrong, on one of wizard (any
wiz) steps because Next button can be disabled (on significant time),
especially on big clusters or in case of slow connection speed, or bad ping.
We have many places where we disable "Next" button while we do some background
operations/calculations. Usually this are requests on
validations/recommendations. Sometimes this can take a significant time frame,
before we will enable Next button. At the same time user is not aware why Next
button is disabled and he cannot proceed to next step. We should give user a
visual feedback that we are doing some calculations and that's why Next button
is disabled. The easiest way is, to switch Next button on spinner while we do
our background stuff.
