>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 2.2.1
>            Reporter: Lantao Jin

> In MapReduce, we can get the submit hostname via checking the value of 
> configuration {{mapreduce.job.submithostname}}. It can help infra team or 
> other people to do support work and debug. Bu in Spark, the information is 
> not included.
> In a big company,  spark infra team can get the submit host list of all 
> applications in a clusters. It can help them to control the submition,  unify 
> upgrade and find the bad jobs where it submitted.
> Then, I suggest to set the submit hostname in spark internal with name 
> {{spark.submit.hostname}}, spark user can not set it ( any manually set will 
> be override).
