>             Project: Spark
>          Issue Type: Bug

>    Affects Versions: 2.1.0

> after patch SPARK-17387 was applied -- Sparkconf object is ignored when launching SparkContext programmatically via python from spark-submit:
> https://github.com/apache/spark/blob/master/python/pyspark/context.py#L128:
> in case when we are running python SparkContext(conf=xxx) from spark-submit:
>     conf is set, conf._jconf is None ()
>     passed as arg  conf object is ignored (and used only when we are launching java_gateway).
> how to fix:
> python/pyspark/context.py:132
> {code:title=python/pyspark/context.py:132}
>         if conf is not None and conf._jconf is not None:
>             # conf has been initialized in JVM properly, so use conf directly. This represent the
>             # scenario that JVM has been launched before SparkConf is created (e.g. SparkContext is
>             # created and then stopped, and we create a new SparkConf and new SparkContext again)
>             self._conf = conf
>         else:
>             self._conf = SparkConf(_jvm=SparkContext._jvm)
> +             if conf:
> +                 for key, value in conf.getAll():
> +                     self._conf.set(key,value)
> +                     print(key,value)
> {code}
