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

    [ https://issues.apache.org/jira/browse/SPARK-5439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14652456#comment-14652456 ] 

Marcelo Vanzin commented on SPARK-5439:
---------------------------------------

There are 3 ways to get the app id:

- Calling {{SparkContext.applicationId}}
- Using a listener and processing {{SparkListenerApplicationStart}}
- If using the launcher library, this will be provided by SPARK-8673.

I don't see what else needs to be done here.
