[jira] [Created] (YARN-11847) getGroupsForUser may be invoked on a null

John Doe created YARN-11847:
-------------------------------

             Summary: getGroupsForUser may be invoked on a null
                 Key: YARN-11847
                 URL: https://issues.apache.org/jira/browse/YARN-11847
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 3.4.1
            Reporter: John Doe


`setRMAdmin()` in `DefaultRMAdminRequestInterceptor` can set `rmAdminProxy` to `null`; after that, if we invoke `getGroupsForUser`, a null pointer exception occurs.
