---------------------------------------

Hi Zhenzhong,
the parallelism and user defined parameters are already available in the web interface.
The URL http://localhost:8081/jobs/<JOBID>/config returns the parallelism and all user defined parameters. For registering the user defined parameters, you have to pass them to the execution config's global job parameters. Its a very simple interface you need to implement to expose the key value pairs.
Flink's {{ParameterTool}} utility also implements that interface:
{code}
final ParameterTool pt = ParameterTool.fromPropertiesFile(args[0]);
see.getConfig().setGlobalJobParameters(pt);
{code}
I think its easy to expose the job entry class using that mechanism as well.
What do you mean by the "jar ID" ?

> From declarative, reconcilation based job management perspective, there is a need to identify the job jar id, and all job parameters for a running job to determine if the current job is up to date. 
> I think these information needs to be available through the job manager rest call (/jobs/$id).
> * Jar ID
> * Job entry class
> * parallelism
> * all user defined parameters
