> Issue Type: Improvement
> Components: Execution - Flow
> Affects Versions: 1.7.0
> Reporter: Deneche A. Hakim
> Assignee: Deneche A. Hakim
> Priority: Minor

> Currently, rpc thread can block when trying to deliver a cancel or early
> termination message to a blocked fragment executor.
> Foreman already uses an EventProcessor to avoid such scenarios.
> FragmentExecutor could be improved to avoid blocking rpc threads as well
