QUESTION
I am using case class in Scala (2.12.8) Apache Flink (1.9.1) application. I get the following exception when I run the code below Caused by: java.lang.NoSuchMethodError: scala.Product.$init$(Lscala/Product;)V.
NOTE: I have used the default constructor as per the suggestion ( java.lang.NoSuchMethodException for init method in Scala case class) but that does not work in my case

Install zignal
You can use zignal like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
