Thomas Weise commented on FLINK-15918:
--------------------------------------
[~trohrmann] our users rely on the metric to monitor their jobs. Continuously
increasing uptime is interpreted as necessary for a healthy job. This
assumption is broken with the recent change.
> This change of behavior exists since 1.9.0 if
>{{jobmanager.execution.failover-strategy: region}} is configured, which we do
>in the default flink-conf.yaml.
And the change if behavior is not present in 1.9 when above setting is not
present in flink-conf.yaml. It is, therefore, a regression for 1.10.
> Uptime Metric not reset on Job Restart

> *Description*
> The {{uptime}} metric is not reset when the job restarts, which is a change
> in behavior compared to Flink 1.8.
> This change of behavior exists since 1.9.0 if
> {{jobmanager.execution.failover-strategy: region}} is configured,
> which we do in the default flink-conf.yaml.
> *Workarounds*
> Users that find this behavior problematic can set {{jobmanager.scheduler:
> legacy}} and unset {{jobmanager.execution.failover-strategy: region}} in
> their {{flink-conf.yaml}}
> *How to reproduce*
> trivial
> *Expected behavior*
> This is up for discussion.
