Zhijie Shen created YARN-3393: --------------------------------- Summary: Getting application(s) goes wrong when app finishes before starting the attempt Key: YARN-3393 URL: https://issues.apache.org/jira/browse/YARN-3393 Project: Hadoop YARN Issue Type: Bug Components: timelineserver Reporter: Zhijie Shen Assignee: Zhijie Shen Priority: Critical
When generating app report in ApplicationHistoryManagerOnTimelineStore, it checks if appAttempt == null. {code} ApplicationAttemptReport appAttempt = getApplicationAttempt(app.appReport.getCurrentApplicationAttemptId()); if (appAttempt != null) { app.appReport.setHost(appAttempt.getHost()); app.appReport.setRpcPort(appAttempt.getRpcPort()); app.appReport.setTrackingUrl(appAttempt.getTrackingUrl()); app.appReport.setOriginalTrackingUrl(appAttempt.getOriginalTrackingUrl()); } {code} However, {{getApplicationAttempt}} doesn't return null but throws ApplicationAttemptNotFoundException: {code} if (entity == null) { throw new ApplicationAttemptNotFoundException( "The entity for application attempt " + appAttemptId + " doesn't exist in the timeline store"); } else { return convertToApplicationAttemptReport(entity); } {code} They code isn't coupled well. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
