Review comment:
We should call the `Async` version if we want to asynchronously run
`onJobSubmitted`. It's not only we return in the same thread in
`JobClusterExecutor` implementation but `CompletableFuture.thenAccept` is
always possibly called in current thread if the future is completed when
`thenXXX` called.
