-------------------------------
Summary: TestBalancer#testBalancerWithKeytabs should reset
KerberosName in test case setup
Key: HDFS-9888
URL: https://issues.apache.org/jira/browse/HDFS-9888
Project: Hadoop HDFS
Issue Type: Test
Reporter: Xiao Chen
Assignee: Xiao Chen
Priority: Minor
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.
