[jira] [Created] (YARN-11953) Fix authentication type checking in Capacity Scheduler UI
Benjamin Teke created YARN-11953:
------------------------------------
Summary: Fix authentication type checking in Capacity Scheduler UI
Key: YARN-11953
URL: https://issues.apache.org/jira/browse/YARN-11953
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Benjamin Teke
Capacity Scheduler UI currently [checks |https://github.com/apache/hadoop/blob/1995d34a54be4e8cc928b58cd0d57d3698462ebd/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-capacity-scheduler-ui/src/main/webapp/src/lib/api/YarnApiClient.ts#L245]the {{hadoop.security.authentication}} config for ensuring what the http authentication type is (to see if the user.name param needs to be added for requests). This is incorrect, {{hadoop.http.authentication.type}} controls the actual webUI authentication type. This causes an issue where if the global auth type is kerberos, but the webUIs use simple, YARN will reject every query made by the Capacity Scheduler UI. To fix this the auth checks should use {{hadoop.http.authentication.type.}}
