Li Lu commented on YARN-5440: ----------------------------- I cannot reproduce the UT failure locally either. [~xgong] could you please open a separate JIRA to trace the UT failure? Patch generally LGTM. One question is that what will happen if the user turn off timeline service but enable AHS in the config? > Use AHSClient in YarnClient when TimelineServer is running > ---------------------------------------------------------- > > Key: YARN-5440 > URL: https://issues.apache.org/jira/browse/YARN-5440 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.9.0 > Reporter: Xuan Gong > Assignee: Xuan Gong > Attachments: YARN-5440.1.patch > > > In YarnClient, depends on whether we enable > yarn.timeline-service.generic-application-history.enabled, the AHSClient will > not be used. But the AHSClientService is enabled by default when we start the > TimelineServer which means we are able to get history information for > applications/applicationAttempts/containers by using ahsClient when the > TimelineServer is running. So, we do not have to reply on this deprecated > configuration to get history information by using YarnClient. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
