I am not a UI expert, just want to make sure a few cases are covered by the patch # since this is a CS only feature, pls make sure nothing breaks when FS is enabled # does the table support paging? > Add diagnostics for outstanding resource requests on app attempts page > ---------------------------------------------------------------------- > > Key: YARN-9567 > URL: https://issues.apache.org/jira/browse/YARN-9567 > Project: Hadoop YARN > Issue Type: Sub-task > Components: capacityscheduler > Reporter: Tao Yang > Assignee: Tao Yang > Priority: Major > Attachments: YARN-9567.001.patch, YARN-9567.002.patch, > image-2019-06-04-17-29-29-368.png, image-2019-06-04-17-31-31-820.png, > image-2019-06-04-17-58-11-886.png, image-2019-06-14-11-21-41-066.png, > no_diagnostic_at_first.png, > show_diagnostics_after_requesting_app_activities_REST_API.png > > > Currently on app attempt page we can see outstanding resource requests, it > will be helpful for users to know why if we can join diagnostics of this app > with these. > Discussed with [~cheersyang], we can passively load diagnostics from cache of > completed app activities instead of actively triggering which may bring > uncontrollable risks. > For example: > (1) At first we can see no diagnostic in cache if app activities not > triggered below the outstanding requests. > !no_diagnostic_at_first.png|width=793,height=248! > (2) After requesting the application activities REST API, we can see > diagnostics now. > !show_diagnostics_after_requesting_app_activities_REST_API.png|width=1046,height=276! > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
