> 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.
