-----------------------------------------
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.
