Gary Yao commented on FLINK-12526:
----------------------------------
I think we won't change the execution graph significantly in the near future.
It should be fine to start working on this issue. What do you think [~zhuzh]?
> Remove STATE_UPDATER in ExecutionGraph

> Components: Runtime / Coordination
> Reporter: vinoyang
> Assignee: vinoyang
> Priority: Minor
>
> Since {{ExecutionGraph}} can only be accessed from a single

> {{AtomicReferenceFieldUpdater<ExecutionGraph, JobStatus> STATE_UPDATER}} from
> {{ExecutionGraph}}.
