             Summary: Cannot set up KDC from scratch
                 Key: IMPALA-10340
                 URL: https://issues.apache.org/jira/browse/IMPALA-10340
             Project: IMPALA
          Issue Type: Bug
          Components: Security
    Affects Versions: Impala 4.0
            Reporter: Attila Doroszlai
            Assignee: Attila Doroszlai


Running {{bin/kerberos/experimental-kerberos-setup.sh}} without existing mini cluster fails with the following error after it installs required packages:

{code}
bin/kerberos/experimental-kerberos-setup.sh: line 50: KRB5_CONFIG: unbound variable
{code}

{{experimental-kerberos-setup.sh}} sources {{impala-config.sh}}, which uses {{testdata/cluster/admin is_kerberized}} to check if the cluster is kerberized.  If it is not, all variables exported by {{minikdc_env.sh}} are including {{KRB5_CONFIG}} are unset.  The problem is that this happens even if the cluster is not yet created.

However, kerberized cluster cannot be created without installing KDC first, so this is catch 22.
