Thanks! > 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: 2.1.1-beta, 3.0.0-alpha1 > Reporter: Chris Nauroth > Assignee: Dmytro Kabakchei > Fix For: 3.0.0-alpha1 > > Attachments: HADOOP-9888.001.patch > > > {{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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
