Zili Chen commented on FLINK-15129:
-----------------------------------
"but currently we always return an already completed future that contains the
JobClient"
in {{AbstractSessionClusterExecutor}} we return a uncompleted future of the
{{JobClient}}.
> Return JobClient instead of JobClient Future from executeAsync()

> Key: FLINK-15129
> URL: https://issues.apache.org/jira/browse/FLINK-15129
> Project: Flink
> Issue Type: Sub-task
> Components: API / DataSet, API / DataStream
> Reporter: Aljoscha Krettek
> Priority: Major
>
> Currently, users have to write this when they want to use the {{JobClient}}:
> {code}
> CompletableFuture<JobClient> jobClientFuture = env.executeAsync();
> JobClient jobClient = jobClientFuture.get();
> // or use thenApply/thenCompose etc.
> {code}
> instead we could always return a {{JobClient}} right away and therefore
> remove one step for the user.
> I don't know if it's always the right choice, but currently we always return
> an already completed future that contains the {{JobClient}}. In the future we
> might want to return a future that actually completes at some later point, we
> would not be able to do this if we directly return a {{JobClient}} and would
> have to block in {{executeAsync()}}.
