@irvingc 怎么解决啊

[tovbinm]

This is most likely due to wrong Scala / Spark version.

[BhaveshMandalkar]

So which is the correct version to solve this issue?

[tovbinm]

I think it was compiled to work with Spark 2.1.0.

[BhaveshMandalkar]

Can you please help me more. I am build the jar against spark 2.1.0 but still get the error. Please tell what's wrong in my pom.xml.
