> Currently, Flink has the FlinkUserCodeClassLoader, which is using to load user’s class. However, the user class and the system class are all loaded by the system classloader in the perjob mode. This introduces some conflicts.
> This document[1] gives a proposal that makes the FlinkUserClassLoader load the user class in perjob mode. (disscuss with Till[2])
