[~rdblue]: Dont know if it was this or the updated jar file, but between the two of these, one of them fixed my issue. Thanks!

> Apparently in some much older version of ASM (3), {{ClassVisitor}} was an interface and not an abstract class. Said much older version can be found in some Hadoop libs or older Spark libs, and ends up in the classpath with CDH's spark 2.
> The simplest solution is to shadow ASM, e.g. using JarJAr Links. The following produces an assembly jar that does not have this issue:
> {code}
> echo 'rule org.objectweb.asm.** org.apache.toree.shadow.@0' >relocate.rules
> java -jar jarjar-1.4.jar process relocate.rules toree.jar toree-relocated.jar
> {code}
> ASM is a dependency of ClassUtil, for which [an issue on this is currently open|https://github.com/bmc/classutil/issues/19], but the author says he may not want to shadow ASM, so I thought maybe you might want to.
