------------------------------------
Summary: Kerberos: when unable to connect to KDC admin, need to
inform user
Key: AMBARI-9324
URL: https://issues.apache.org/jira/browse/AMBARI-9324
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Robert Levas
Assignee: Robert Levas
Fix For: 2.0.0
This appears to be happening when the KDC and/or KDC Admin hosts do not point
to a valid KDC, and when the relevant KDC does not _handle_ the indicated realm.
For the *host* issue, (in the cases that I tested), a
{{org.apache.ambari.server.serveraction.kerberos.KerberosKDCConnectionException}}
is being thrown but not caught to re-throw a
{{java.lang.IllegalArgumentException}}, which would generate the expected 400
error.
For the *realm* issue, the following error string is not being captured by the
logic to produce a
{{org.apache.ambari.server.serveraction.kerberos.KerberosRealmException}}.
{code}
kadmin: Cannot find KDC for requested realm while initializing kadmin interface
{code}
In any case,
{{org.apache.ambari.server.serveraction.kerberos.KerberosRealmException}} is
not being caught to re-throw a {{java.lang.IllegalArgumentException}}, which
would generate the expected 400 error.
