Guowei Ma created FLINK-13993:
---------------------------------

             Summary: Using FlinkUserCodeClassLoaders to load the user class in the perjob mode
                 Key: FLINK-13993
                 URL: https://issues.apache.org/jira/browse/FLINK-13993
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.9.0, 1.10.0
            Reporter: Guowei Ma


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])
