Aljoscha Krettek updated FLINK-11889:
-------------------------------------
    Description: 
During the [ML 
discussion|https://lists.apache.org/thread.html/b8d2f3209e7ca7467af6037383ade6c14c35276f7acb2bbbc9a50c0f@%3Cdev.flink.apache.org%3E]
 of 
[FLIP-34|https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=103090212]
 we realised that it would be beneficial for this new feature to replace the 
existing "stop" functionality. The current "stop" functionality cannot be used 
because no real-world sources support the functionality. Therefore, I think it 
is save to remove because it should not break existing workflows.

The issue proposes completely removing the old stop feature, introduced via 
FLINK-2111, as preparation for 
[FLIP-34|https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=103090212].

We have to be careful when doing this because it touches quite a few things. 
Basically, we have to do a manual revert of this commit: 
https://github.com/apache/flink/commit/bdd4024e20fdfb0accb6121a68780ce3a0c218c0
