----------------------------------------
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}
