Hi Flink users,
Flink Jobmanager throw a NotSerializableException when i used
JobMasterGateway to get ExecutionGraph of a specific job with
message RequestJob(jobID). Blow is the detail of Exception:
[ERROR] [akka.remote.EndpointWriter] - Transient association error (association
remains live)
java.io.NotSerializableException:

So,is it a bug or the way to get job’s executionGraph is invalid.
