Zhijie Shen commented on YARN-3700:
-----------------------------------
[~xgong], thanks for the patch. Some comments bellow:
1. Actually not webapp will be affected by this config. REST API and
application history protocol will be too. Can we rename it to
"yarn.timeline-service.generic-application-history.max-applications" ?
{code}
1450 /** Defines how many applications can be loaded into timeline service
web ui.*/
1451 public static final String TIMELINE_SERVICE_WEBAPP_MAX_APPS =
1452 TIMELINE_SERVICE_PREFIX + "webapp.max-applications";
{code}
2. In TestApplicationHistoryClientService, would you please validate if the
applications are retrieved in descending order according to submission time (if
I remember it correctly).
3. I'm thing if it is good support override the default config by passing the
query param in url, such as "?max-applications=100". Thoughts?
