problem

This error occurs when the case class parameter exceeds 22.

The case class has a maximum of 22 parameters at the time of the Scala 2.11.x version, and if this parameter cannot be upgraded (for example, current Spark relies on 2.10.x) What do I do? Solution Solutions

Here's an example of 26 parameters, the rest of the situation, and so on
