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

ah, I just think that we can give a runtime configuration for every running 
job, and this maybe helpful for user.Now the configuration can be set in many 
place and users may confuse by this, since they are not very sure which 
configuration are taking effect.

> Show the in-use config of job to users

> Now the config can be set from global cluster configuration and single job 
> code , since we can't absolutely sure that which config is in-use except we 
> check it in the start-up log. I think maybe we can show the in-use config of 
> job to users and this can be helpful!
