Sean Owen updated SPARK-22744:
------------------------------
Priority: Minor (was: Major)
> Add a configuration to show the application submit hostname
> -----------------------------------------------------------
>
> Key: SPARK-22744
> URL: https://issues.apache.org/jira/browse/SPARK-22744
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.2.1
> Reporter: Lantao Jin
> Priority: Minor
>
> 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.
> Then, I suggest to introduce a new configuration parameter,
> {{spark.submit.hostname}}, which will be set automatically by default, but it
> also allows to set this to an user defined hostname if needed (e.g, using an
> user node instead of Livy server node).
