David McLaughlin reopened AURORA-894: ------------------------------------- Assignee: (was: Maxim Khutornenko) > Server updater should watch healthy instances > --------------------------------------------- > > Key: AURORA-894 > URL: https://issues.apache.org/jira/browse/AURORA-894 > Project: Aurora > Issue Type: Epic > Components: Scheduler > Reporter: Maxim Khutornenko > Labels: 2015-Q2 > > Instead of starting the {{minWaitInInstanceRunningMs}} (aka {{watch_secs}}) > countdown when an instance reaches RUNNING state, the updater should rely on > the first successful health check instead. This will potentially speed up > updates as the {{minWaitInInstanceRunningMs}} will no longer have to be > chosen based on the worst observed instance startup/warmup delay but rather > as a desired health check duration according to the following formula: > {noformat} > minWaitInInstanceRunningMs = interval_secs x num_desired_healthchecks x 1000 > {noformat} > where: > {{interval_secs}} - > https://github.com/apache/incubator-aurora/blob/master/docs/configuration-reference.md#healthcheckconfig-objects > {{num_desired_healthchecks}} - the desired number of OK health checks to > observe before declaring an instance updated successfully > > The above would allow every instance to start watching interval depending on > the individual instance performance and potentially exit updater earlier. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
