gabrywu opened a new issue, #28887: URL: https://github.com/apache/beam/issues/28887
### What would you like to happen? Our job is running on a flink runner. And our flink cluster has a `org.apache.flink.runtime.security.contexts.SecurityContext`, which runs user codes within a `UserGroupInformation.createProxyUser.doAs`. However FileSystems always use the login user to do the kerberos auth and access hadoop files using this user, is it possible to use proxy user to access hadoop files? ### Issue Priority Priority: 2 (default / most feature requests should be filed as P2) ### Issue Components - [ ] Component: Python SDK - [X] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
