Subject [jira] Updated: (HADOOP-6526) Need mapping from long principal names to local OS user names
Date Tue, 27 Apr 2010 01:49:32 GMT

Konstantin Boudnik updated HADOOP-6526:
---------------------------------------

    Attachment: 3595485.patch

Another issue is that the setting affects _all_ tests. This is especially bad for tests which
are running on an actual cluster but from the source workspace i.e. Herriot tests. This settings
forces default realm to be set to APACHE.ORG which is non-sensical in environments with different
realm names.

A better way is to set this property directly in the functional tests requiring this config
file. Other tests shouldn't be affected.

This is dirty hack to workaround the problem, although we shouldn't be modifying the whole
build just because of a couple of tests requiring a custom config file.

> 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.
