> Omit sending checkpoint barriers when the execution graph is not running

> Key: FLINK-1808

> Project: Flink
> Issue Type: Improvement
> Components: Streaming
> Reporter: Paris Carbone
> Assignee: Paris Carbone
>
> Currently the StreamCheckpointCoordinator sends barrier requests even when
> the executionGraph is in FAILING or RESTARTING status which results in
> unneeded potential communication and space overhead until the job restarts
> again. It should therefore simply omit sending barriers requests when the
> execution graph is not in a RUNNING state.
