Github user StephanEwen commented on the issue:

    Hi @summerleafs!
    I think we cannot use this approach to fix this. The most important thing is that this
introduces a blocking operation (`.get()` on the future) in the call, which will make the
while `schedueEager()` call block. Since the ExecutionGraph runs in an actor-style context,
methods must never block. Everything must be implemented with future completion functions.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
