             Summary: Make admin check for SCM HA cluster
                 Key: HDDS-5205
                 URL: https://issues.apache.org/jira/browse/HDDS-5205
             Project: Apache Ozone
          Issue Type: Task
            Reporter: Bharat Viswanadham


By default, the user started principal is added to scmAdminUsernames.

    String scmUsername = UserGroupInformation.getCurrentUser().getUserName();
    if (!scmAdminUsernames.contains(scmUsername)) {
      scmAdminUsernames.add(scmUsername);
    }

In HA cluster, when kinit with scm2 principal when scm1 is leader, we get access denied as we check getUserName() and also when adding to adminlist we use getUserName.

In OM we don't have this kind of issue, as getShortUserName() is used.


{code:java}
  String omSPN = UserGroupInformation.getCurrentUser().getShortUserName();
    if (!ozAdmins.contains(omSPN)) {
      ozAdmins.add(omSPN);
    }
{code}
