Vinod Kumar Vavilapalli commented on YARN-2181: ----------------------------------------------- Tx for the UI, it looks great! Glanced at the patch, one comment - did not do a detailed review - we don't usually name transitions based on what happens in it. For e.g. UpdatePreemptionMetricsTransition should instead be called something like ContainerFinishedTransition and other ContainerFinished***Transitions can inherit or invoke it. It's likely this patch will conflict with YARN-415, please have a look at it and figure out the order of the patches. Thanks.. > Add preemption info to RM Web UI and add logs when preemption occurs > -------------------------------------------------------------------- > > Key: YARN-2181 > URL: https://issues.apache.org/jira/browse/YARN-2181 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager, webapp > Affects Versions: 2.4.0 > Reporter: Wangda Tan > Assignee: Wangda Tan > Attachments: YARN-2181.patch, YARN-2181.patch, YARN-2181.patch, > YARN-2181.patch, YARN-2181.patch, YARN-2181.patch, YARN-2181.patch, > YARN-2181.patch, YARN-2181.patch, YARN-2181.patch, YARN-2181.patch, > YARN-2181.patch, YARN-2181.patch, YARN-2181.patch, YARN-2181.patch, > application page-1.png, application page.png > > > We need add preemption info to RM web page to make administrator/user get > more understanding about preemption happened on app, etc. > And RM logs should have following properties: > * Logs are retrievable when an application is still running and often flushed. > * Can distinguish between AM container preemption and task container > preemption with container ID shown. > * Should be INFO level log. -- This message was sent by Atlassian JIRA (v6.2#6252)
