Spark - Scala-Java interoperablity

[Ramesh Mathikumar <me...@googlemail.com.INVALID>]

Hi Team,

A quick question from my side.

Can I use spark-submit which contains both java and scala in a single
workflow. By single workflow I mean main program is in Java (Wrapped
in Spark) and it calls a module to calculate something on the payload
which is in Scala (wrapped in Spark).

Are there any compatibility / interoperability issues around?

Regards,
Ramster

That should be fine. The JVM doesn't care how the bytecode it is
executing was produced. As long as you were able to compile it
together - which sometimes means using plugins like scala-maven-plugin
for mixed compilation - the result should be fine.
