spark 2.1.1 : Parsed JSON values do not match with class constructor

Question

I've a strange problem with spark 2.1.1 and json4s.jackson.

I upgraded my streaming project from spark 1.5.1. Now when I execute code in IDE everything works fine.

But after assembly and code standalone execution with spark-submit

I got the following error

Caused by: org.json4s.package$MappingException: Parsed JSON values do not match with class constructor
args=
arg types=
constructor=  

My Environemnt:

• spark=2.1.1,
• scala=2.11,
• json4s-jackson=3.2.11

Has somebody has faced the same problem before? If yes, how did you solve it?

Many thanks.
