Yang Wang commented on FLINK-19358:
-----------------------------------

Thanks [~trohrmann] for sharing the information about FLIP-194. I have 
carefully gone through the design doc and agree that it is the right direction 
to support multiple jobs in the same application. So I also lean to defer this 
ticket and not introduce such a special case.

 

Actually, we never guarantee that the job id(even the random id) is unique 
across different Flink clusters.

 

> when submit job on application mode with HA,the jobid will be 0000000000
