Chesnay Schepler updated FLINK-27954:
-------------------------------------
Description:
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.
