In some local environments, TestBalancer#testBalancerWithKeytabs may fail. Specifically, running itself passes, but running TestBalancer suite always fail. This is due to:
- Kerberos setup is done at the test case setup
- static variable KerberosName#defaultRealm is set when class initialization - before testBalancerWithKeytabs setup
- local default realm is different than test case default realm
This is mostly an environment specific problem, but let's not make such assumption in the test.
