             Summary: YARN Services with simple authentication doesn't respect current UGI
                 Key: YARN-9385
                 URL: https://issues.apache.org/jira/browse/YARN-9385
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: security, yarn-native-services
            Reporter: Todd Lipcon


The ApiServiceClient implementation appends the current username to the request URL for "simple" authentication. However, that username is derived from the 'user.name' system property instead of the current UGI. That means that username spoofing via the 'HADOOP_USER_NAME' variable doesn't take effect for HTTP-based calls in the same manner that it does for RPC-based calls.
