PR: https://github.com/apache/spark/pull/539
> App name set in SparkConf (not in JVM properties) not respected by Yarn
> backend
> -------------------------------------------------------------------------------

> Key: SPARK-1631
> URL: https://issues.apache.org/jira/browse/SPARK-1631
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Reporter: Marcelo Vanzin
> Assignee: Marcelo Vanzin
>
> When you submit an application that sets its name using a SparkContext
> constructor or SparkConf.setAppName(), the Yarn app name is not set and the
> app shows up as "Spark" in the RM UI.
> That's because YarnClientSchedulerBackend only looks at the system properties
> to look for the app name, instead of looking at the app's config.
> e.g., app initializes like this:
> {code}
> val sc = new SparkContext(new SparkConf().setAppName("Blah"));
> {code}
> Start app like this:
> {noformat}
> ./bin/spark-submit --master yarn --deploy-mode client blah blah blah
> {noformat}
> And app name in RM UI does not reflect the code.
