             Summary: Test Kerberos Client fail after reenter of right realm value
                 Key: AMBARI-24054
                 URL: https://issues.apache.org/jira/browse/AMBARI-24054
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.7.0
            Reporter: Sandor Molnar
            Assignee: Sandor Molnar
             Fix For: 2.7.0


Test Kerberos Client fail after reenter of right realm value during kerberos enabling

STR:
1)Start of kerberos enabling
2)Select existing MIT
3)Go to Configure Kerberos page
4)Set wrong "Realm name" value. As an example: "example.com" (expected EXAMPLE.COM)
5)Go to Install and Test Kerberos Client step
6)Wait of Test Kerberos Client fail
7)Back to Configure Kerberos step
8)Enter right "Realm name" value 
9)Go to Install and Test Kerberos Client step

Expected:
Test Kerberos Client pass successfully

Actual:
Test Kerberos Client fail

The supposed main reason is using old realm value for principals creation:
{code:java}
2018-05-30 11:13:38,895 - Failed to create principal, cl1-053018@example.com - Failed to create service principal for cl1-053018@example.com
STDOUT: Authenticating as principal admin/admin@EXAMPLE.COM with existing credentials.

STDERR: WARNING: no policy specified for cl1-053018@example.com; defaulting to no policy
add_principal: No such entry in the database while creating "cl1-053018@example.com".

Administration credentials NOT DESTROYED.
{code}
This is happening only using MySQL.
