[jira] [Created] (FLINK-24680) Expose UserCodeClassLoader in OperatorCoordinator.Context for registering release hooks

Qingsheng Ren created FLINK-24680:
-------------------------------------

             Summary: Expose UserCodeClassLoader in OperatorCoordinator.Context for registering release hooks
                 Key: FLINK-24680
                 URL: https://issues.apache.org/jira/browse/FLINK-24680
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.14.0
            Reporter: Qingsheng Ren
             Fix For: 1.15.0


Currently `OperatorCoordinator.Context` only exposes `ClassLoader` for accessing user code class loader, which doesn't support adding release hooks in `OperatorCoordinator`, like sync releasing class loader and closing operator coordinator. 

We need to expose `UserCodeClassLoader` in the context fo registering hooks in coordinator.
