-----------------------------------
Summary: Propose to print Scala version in "spark-submit
--version" command
Key: SPARK-17686
URL: https://issues.apache.org/jira/browse/SPARK-17686
Project: Spark
Issue Type: Improvement
Components: Spark Submit
Reporter: Saisai Shao
Priority: Minor
Currently we have a use case that needs to upload different jars to Spark
according to scala version. For now only after launching Spark application can
we know which version of Scala it depends on. It makes hard for some services
which needs to support different Scala + Spark versions to pick the right jars.
So here propose to print out Scala version according to Spark version in
"spark-submit --version", so that user could leverage this output to make the
choice without needing to launching application.
