[jira] [Commented] (SPARK-28762) Read JAR main class if JAR is not
located in local file system
[ https://issues.apache.org/jira/browse/SPARK-28762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16911563#comment-16911563 ]

-------------------------------------
Hi [~dongjoon], I'm not sure if you meant to change the Fix Version field, since I believe Spark 3.0.0 hasn't been released yet? :)
Do you think the feature is reasonable, by the way?

> Key: SPARK-28762
> URL: https://issues.apache.org/jira/browse/SPARK-28762
> Project: Spark
> Issue Type: New Feature
> Components: Deploy, Spark Core, Spark Submit
> Affects Versions: 3.0.0
> Reporter: Ivan Gozali
> Priority: Minor
>
> Currently, {{spark-submit}} doesn't attempt to read the main class from a Spark app JAR file if the scheme of the primary resource URI is not {{file}}. In other words, if the JAR is not in the local file system, it will barf.
> It would be useful to have this feature if I deploy my Spark app JARs in S3 or HDFS.
> If it makes sense to maintainers, I can take a stab at this - I think I know which files to look at.
