-------------------------------------
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.
