> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination, Runtime / REST
> Affects Versions: 1.15.0
> Reporter: Chesnay Schepler
> Assignee: Weijie Guo
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.16.2, 1.18.0, 1.15.5

>
> The {{JobVertexFlameGraphHandler}} relies internally on the {{JobVertexThreadInfoTracker}} which calls
> {{ResourceManagerGateway#requestTaskExecutorThreadInfoGateway}} to get a gateway for requesting the thread info from the task executors. Since this gateway is not serializable it would categorically fail if called from a standby dispatcher.
> Instead this should follow the logic of the {{MetricFetcherImpl}}, which requests addresses instead and manually connects to the task executors.
