> Allow setting YARN_CONF_DIR from spark argument

>                 Key: SPARK-7706
>                 URL: https://issues.apache.org/jira/browse/SPARK-7706
>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Submit
>    Affects Versions: 1.3.1
>            Reporter: Shaik Idris Ali
>            Priority: Minor
>              Labels: oozie, yarn

> Currently in SparkSubmitArguments.scala when master is set to "yarn" (yarn-cluster mode)
> https://github.com/apache/spark/blob/b1f4ca82d170935d15f1fe6beb9af0743b4d81cd/core/src/main/scala/org/apache/spark/deploy/SparkSubmitArguments.scala#L236
> Spark checks if YARN_CONF_DIR or HADOOP_CONF_DIR is set in EVN.
> However we should additionally allow passing YARN_CONF_DIR from command line argument
this is particularly handy when Spark is being launched from schedulers like OOZIE or FALCON.
> Reason being, oozie launcher App starts in one of the container assigned by Yarn RM and
we do not want to set YARN_CONF_DIR in ENV for all the nodes in cluster. Just passing the
argument like -yarnconfdir with conf dir (ex: /etc/hadoop/conf) should avoid setting the ENV
variable.
> This is blocking us to onboard spark from oozie or falcon. Thanks.
