--------------------------------------
A similar problem was encountered in a lower version, I think it needs to be
fixed in master as well, otherwise, others may encounter problems when using
ExecutionGraph#getJobConfiguration in the future
> User set job configuration can not be retirieved from JobGraph and
> ExecutionGraph

> Key: FLINK-29146
> URL: https://issues.apache.org/jira/browse/FLINK-29146
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.16.0
> Reporter: Shuiqiang Chen
> Priority: Major
>
> Currently, when building an ExecutionGraph, it requires to set the job
> specific information (like job id, job name, job configuration, etc) and most
> of them are from JobGraph.But I find that the configuration in JobGraph is a
> new Configuration instance when the JobGraph is built, and it does not
> contain any user set configuration. As a result, we are not able retrieve the
> use specified job configuration in ExecutionGraph built from JobGraph during
> execution runtime.
> BTW, in StreamExecutionEnvironment, it seems that job configurations that not
> contained in built-in options will be ignored when calling
> StreamExecutionEnvironment.configure(ReadableConfig[, ClassLoader]). However,
> it will be included when constructing a StreamExecutionEnvironment, which
> seems a bit inconsistent. Is it by design?
> {code:java}
> Configuration configuration = new Configuration();
> // These configured string will take effect.
> configuration.setString("k1", "v1");
> configuration.setString("k2", "v2");
> configuration.setString("k3", "v3");
> configuration.set(HeartbeatManagerOptions.HEARTBEAT_TIMEOUT, 300000L);
> final StreamExecutionEnvironment env =
> StreamExecutionEnvironment.getExecutionEnvironment(configuration);
> // These configured string will be ignored.
> configuration.setString("k4", "v4");
> configuration.setString("k5", "v5");
> configuration.setString("k6", "v6");
> env.configure(configuration);
> {code}
