[jira] [Updated] (YARN-3393) Getting application(s) goes wrong when app finishes before starting the attempt

     [ https://issues.apache.org/jira/browse/YARN-3393?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vinod Kumar Vavilapalli updated YARN-3393:
------------------------------------------
    Fix Version/s: 2.6.1

Pulled this into 2.6.1. The patch applied cleanly for the most part, had to make one change to not use the java-7 style exception handling.

Ran compilation and TestApplicationHistoryManagerOnTimelineStore before the push.

> 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.
