Subject Re: How to export a project to a JAR in Scala IDE for eclipse Correctly?
Date Wed, 27 Jul 2016 06:58:51 GMT
Why don't you install sbt and try sbt assembly to create a scala jar.
You can using this jar to your spark submit jobs.

In case there are additional dependencies these can be passed as --jars
(comma separated jar paths) option to spark submit.
