### What is this PR for? Currently, there's one `spark-scala-parent` module which is shared by multiple scala module. This can reduce code duplication, but bring difficulties for developing spark module. It is not easy for new developers to configure it properly in IDE and run unit test in IDE. This PR is to restructure the spark module: move the code in spark-scala-parent to each scala module (scala-2.11,scala-2.12,scala-2.13), this would cause code duplication, but ease the development phase and maintenance. After this PR, you can run spark unit test directly without any extra configuration in intellij. ### What type of PR is it?
