ASF GitHub Bot commented on FLINK-2111: --------------------------------------- Github user tillrohrmann commented on the pull request: https://github.com/apache/flink/pull/750#issuecomment-182859453 Really good work @mjsax. I had a couple of minor inline comments with respect to the latest commit and some with respect to the overall changes (especially concerning the `decorateMessage` method). Why have you changed the `vendor.js` and the `index.js` file? I thought that these files should stay unchanged. I was wondering whether we shouldn't make the `StoppableSourceStreamTask` and the `StoppableStreamSource` type safe, e.g. enforcing that the `StreamSource` and the `SourceFunction` are actually stoppable. Currently, this is not properly checked/enforced. This should be done by the compiler. > Add "stop" signal to cleanly shutdown streaming jobs > ---------------------------------------------------- > > Key: FLINK-2111 > URL: https://issues.apache.org/jira/browse/FLINK-2111 > Project: Flink > Issue Type: Improvement > Components: Distributed Runtime, JobManager, Local Runtime, > Streaming, TaskManager, Webfrontend > Reporter: Matthias J.
