Subject [jira] Commented: (HADOOP-6526) Need mapping from long principal names to local OS user names
Date Tue, 27 Apr 2010 01:47:33 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6526?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12861202#action_12861202
] 

Konstantin Boudnik commented on HADOOP-6526:
--------------------------------------------

Latest patch introduces {{src/test/krb5.conf}} which is needed by a couple of tests only.
The use of this configuration file for some tests is enabled by the property java.security.krb5.conf.
Kerberos has a bug in the implementation of the logic around this property (see http://bugs.sun.com/view_bug.do?bug_id=6857795)

This badly affects any tests running from under ant environment (i.e. Herriot tests (HADOOP-6332))
and on another hand isn't sufficient for Eclipse environment.

> We need a configurable mapping from full user names (eg. omalley@APACHE.ORG) to local
user names (eg. omalley). For many organizations it is sufficient to just use the prefix,
however, in the case of shared clusters there may be duplicated prefixes. A configurable mapping
will let administrators resolve the issue.
