> Project: Beam
> Issue Type: Bug
> Components: runner-spark
> Reporter: Aviem Zur
> Assignee: Aviem Zur

> Today aggregators and metrics accumulators are instantiated after pipeline is
> traversed, and so, if code that runs on driver accesses these singletons but
> is not part of a closure a {{NullPointerException}} is thrown.
