Sean Owen commented on SPARK-15360:
-----------------------------------
Sounds fine to make sure some better error is raised at least, or shows usage
> Should print spark-submit usage when no arguments is specified
> --------------------------------------------------------------

> Key: SPARK-15360
> URL: https://issues.apache.org/jira/browse/SPARK-15360
> Project: Spark
> Issue Type: Bug
> Components: Spark Submit
> Affects Versions: 2.0.0
> Reporter: Jeff Zhang
> Priority: Minor
>
> In spark 1.6.1, it would print spark-submit usage when calling
> bin/spark-submit without any argument, but in spark 2.0, it would just print
> error, it would be nice to make it consistent with spark 1.6.1

> Exception in thread "main" java.lang.IllegalArgumentException: Missing
> application resource.
