> 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])
