             Summary: Properly set the context ClassLoader when calling OperatorCoordinator on JM side
                 Key: FLINK-24572
                 URL: https://issues.apache.org/jira/browse/FLINK-24572
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.14.0
            Reporter: Yun Gao


Currently when calling methods of user defined OperatorCoordinator on JM side, the context ClassLoader is not set to the user ClassLoader. this might cause some problem.

For example, the Hadoop configuration first chose to use context ClassLoader for locating the configuration files like _core-site.xml ,_ and parse the class out of configuration. If the context ClassLoader is not set properly, the configurations file might be not located or the class might not be created, which might cause confusion to users.
