[jira] [Commented] (SPARK-22372) Make YARN client extend SparkApplication

["Marcelo Vanzin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-22372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16222829#comment-16222829 ] 

Marcelo Vanzin commented on SPARK-22372:
----------------------------------------

I could file a separate bug for that, but {{RestSubmissionClient}} (and standalone's {{Client}}) could also be changed to implement {{SparkApplication}}. Since that would probably be trivial compared to the YARN change, might as well do it in together.

> For SPARK-11035 to work well, at least in cluster mode, YARN needs to implement {{SparkApplication}} so that it doesn't use system properties to propagate Spark configuration from spark-submit.
> There is a second complication, that YARN uses system properties to propagate {{SPARK_YARN_MODE}} on top of other Spark configs. We should take a look at either change that to a configuration, or remove {{SPARK_YARN_MODE}} altogether if possible.
