Subject [jira] [Updated] (HADOOP-7229) Absolute path to kinit in auto-renewal thread
Date Tue, 12 Jul 2011 22:31:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-7229?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aaron T. Myers updated HADOOP-7229:
-----------------------------------

    Release Note: When Hadoop's Kerberos integration is enabled, it is now required that either
{{kinit}} be on the path for user accounts running the Hadoop client, or that the {{hadoop.kerberos.kinit.command}}
configuration option be manually set to the absolute path to {{kinit}}.  (was: It is now required
that either {{kinit}} be on the path for user accounts running the Hadoop client, or that
the {{hadoop.kerberos.kinit.command}} configuration option be manually set to the absolute
path to {{kinit}}.)

Per an offline suggestion from Eli, I'm amending the release note to make it clear that this
is only necessary to configure when security is enabled.

> In the auto-renewal thread for Kerberos credentials in {{UserGroupInformation}}, the
path to {{kinit}} is defaulted to {{/usr/kerberos/bin/kinit}}. This is the default path to
{{kinit}} on RHEL/CentOS for MIT krb5, but not on Debian/Ubuntu (and perhaps others OSes.)
