>             Project: Flink

> Currently, streaming jobs can only be stopped using "cancel" command, what is a "hard"
stop with no clean shutdown.
> The new introduced "terminate" signal, will only affect streaming source tasks such that
the sources can stop emitting data and terminate cleanly, resulting in a clean termination
of the whole streaming job.
> This feature is a pre-requirment for https://issues.apache.org/jira/browse/FLINK-1929
