Hi agura, I refer to the source code of IgniteContext.scala, and notified that the ignite method will do "Ignition.start()" in a try-catch block. And the code I use is listed in this topic: http://apache-ignite-users.70518.x6.nabble.com/How-to-solve-the-22-parameters-limit-under-scala-2-10-in-the-case-class-tc3847.html You can find them in the 6th comment written by me, thanks a lot
