Subject [jira] [Updated] (HADOOP-7229) Absolute path to kinit in auto-renewal thread
Date Mon, 18 Apr 2011 16:58:05 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: It is now required that either {{kinit}} be on the path for both the {{hdfs}}
and {{mapred}} user accounts, or that the {{hadoop.kerberos.kinit.command}} configuration
option be manually set to the absolute path to {{kinit}}.
    Hadoop Flags: [Incompatible change]

Thanks a lot for the review/comments, Owen. I've updated the release note and marked this
as an incompatible change.

> 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.)
