Subject [jira] [Commented] (HDFS-9888) TestBalancer#testBalancerWithKeytabs should reset KerberosName in test case setup
Date Fri, 04 Mar 2016 17:38:40 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15180223#comment-15180223

Xiao Chen commented on HDFS-9888:
---------------------------------

Yes Zhe, HDFS-3016 is not in branch-2.
Additionally, since {{TestBalancer#testBalancerWithKeytabs}} is added by HDFS-9804 which is
not in branch-2, I think trunk is enough for this patch. I've added a link to that jira, so
that if later we're backporting it, we'll bring this as well. Thanks!

> 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.
