----------------------------------------------------------------
I would argue that this is not a bug because there is no guarantee that Mahout
should work with a version of Spark that it's not its current dependency. As is
stated in the FAQ for using Mahout with Spark -
https://mahout.apache.org/users/sparkbindings/faq.html :
"If you are getting method signature like errors, most probably you have
mismatch between Mahout's Spark dependency and actual Spark installed."
The current mahout/pom.xml states that the dependency is Spark 1.6.2 (and not
Spark 2.x), and spark-shell works fine with the 1.6.2 version. So, this bug
should either be closed or be changed to a feature request or something.
