>             Project: Flink
>          Issue Type: Bug
>          Components: Runtime / Metrics
>    Affects Versions: 1.7.2, 1.8.1, 1.9.0
>            Reporter: Kaibo Zhou
>            Priority: Major

> I have run a flink job on kubernetes and use PrometheusPushGatewayReporter, I can see the metrics from the flink jobmanager and taskmanager from the push gateway's UI.
> When I cancel the job, I found the jobmanager's metrics disappear, but the taskmanager's metrics still exist, even though I have set the _deleteOnShutdown_ to true_._
> The configuration is:
> {code:java}
> metrics.reporters: "prom"
> metrics.reporter.prom.class: "org.apache.flink.metrics.prometheus.PrometheusPushGatewayReporter"
> metrics.reporter.prom.jobName: "WordCount"
> metrics.reporter.prom.host: "localhost"
> metrics.reporter.prom.port: "9091"
> metrics.reporter.prom.randomJobNameSuffix: "true"
> metrics.reporter.prom.filterLabelValueCharacters: "true"
> metrics.reporter.prom.deleteOnShutdown: "true"
> {code}
>  
> Other people have also encountered this problem: [https://stackoverflow.com/questions/54420498/flink-prometheus-push-gateway-reporter-delete-metrics-on-job-shutdown].  And another similar issue: FLINK-11457.
>  
> As prometheus is a very import metrics system on kubernetes, if we can solve this problem, it is beneficial for users to monitor their flink jobs.
