jocean.shi commented on FLINK-19358:
------------------------------------

it don't have any disadvantages to add a random jobId, it's very convenience 
for user. The rules of checkpoint、jobHistory、and so on will be the same as 
before.I don't need to modify my code to resolve the sence that all the job 
have the same jobId.

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