[jira] Commented: (HADOOP-6526) Need mapping from long principal
names to local OS user names
[ 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.
