             Summary: OM DB checkpoint servlet not accessible in a secure 
cluster
                 Key: HDDS-5165
                 URL: https://issues.apache.org/jira/browse/HDDS-5165
             Project: Apache Ozone
          Issue Type: Bug
          Components: OM
    Affects Versions: 1.1.0
            Reporter: Vivek Ratnavel Subramanian
            Assignee: Vivek Ratnavel Subramanian


When security and ACL is enabled, but not spnego, the OMDBCheckpointServlet 
throws an error:
{code:java}
10:02:29.094 PM ERROR OMDBCheckpointServlet 
 Permission denied: User principal 'dr.who' does not have access to 
/dbCheckpoint.
 This can happen when Ozone Manager is started with a different user.
 Please append 'dr.who' to OM 'ozone.administrators' config and restart OM to 
grant current user access to this endpoint.{code}

When Spnego is disabled, permissions cannot be checked since HTTP request will 
not have an identity (kerberos principal) which is causing this error.
