Question

I am trying to run the word count example from the Spark website ( http://spark.apache.org/docs/latest/quick-start.html ) in Scala Spark but when I try to spark-submit I get an exception: java.lang.NoClassDefFoundError: scala/runtime/LambdaDeserialize The Spark version is 2.0.1 and the Scala version is 2.12.0

The full trace is here: http://pastebin.com/LEjRTAy4

The example code works fine on spark-shell

Note: Starting version 2.0, Spark is built with Scala 2.11 by default. Scala 2.10 users should download the Spark source package and build with Scala 2.10 support.

use scala 2.11.11
