-------------------------------------
Summary: KerberosName static initialization gets default realm,
which is unneeded in non-secure deployment.
Key: HADOOP-9888
URL: https://issues.apache.org/jira/browse/HADOOP-9888
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 3.0.0, 2.1.1-beta
Reporter: Chris Nauroth
{{KerberosName}} has a static initialization block that looks up the default
realm. Running with Oracle JDK7, this code path triggers a DNS query. In some
environments, we've seen this DNS query block and time out after 30 seconds.
This is part of static initialization, and the class is referenced from
{{UserGroupInformation#initialize}}, so every daemon and every shell command
experiences this delay. This occurs even for non-secure deployments, which
don't need the default realm.
