submit a job issue

[Qihua Yang]

Hi,

We are running a flink cluster in session mode. After the cluster is
launched, no job is running. We want to use REST api to run a job at some
point.
The jobManager already contains a jar when we deploy. We don't want to
upload a new jar by using REST api. Is there any way that I use REST api to
run this jar?
Looks like REST api only can submit a job by running a jar that was
previously uploaded by using REST api.

Thanks,
Qihua
