Akhil PB commented on YARN-7957:
--------------------------------
Below are the service states enums defined.
{code:java}
public enum ServiceState {
ACCEPTED, STARTED, STABLE, STOPPED, FAILED, FLEX, UPGRADING,
UPGRADING_AUTO_FINALIZE;
}
{code}
So for a deployed service,
1. Show both Stop and Delete button when states are
{code:java}
ACCEPTED, STARTED, STABLE, FLEX, UPGRADING, UPGRADING_AUTO_FINALIZE
{code}
2. Show Delete button only when state is
{code:java}
STOPPED
{code}
3. Do not show any buttons when state is
{code:java}
FAILED
{code}
OR if response code is 404 error.

> Key: YARN-7957
> URL: https://issues.apache.org/jira/browse/YARN-7957
> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn-ui-v2
> Affects Versions: 3.1.0
> Reporter: Yesha Vora
> Assignee: Akhil PB
> Priority: Critical
> Attachments: YARN-7957.001.patch

>
> Steps:
> 1) Launch yarn service
> 2) Go to service page and click on Setting button->"Stop Service". The
> application will be stopped.
> 3) Refresh page
> Here, setting button disappears. Thus, user can not delete service from UI
> after stopping application
> Expected behavior:
> Setting button should be present on UI page after application is stopped. If
> application is stopped, setting button should only have "Delete Service"
> action available.
