Subject [jira] Commented: (HADOOP-4429) Misconfigured UNIX Groups Break Hadoop
Date Fri, 17 Oct 2008 14:58:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12640542#action_12640542
] 

Owen O'Malley commented on HADOOP-4429:
---------------------------------------

+1 for the return of DrWho !

Historical background:

Hadoop used to default to "Dr Who" as the user id, if it couldn't figure out your username
from the system properties. It was removed because of the space and the assertion that it
never happened. Introduced in HADOOP-52 and removed by HADOOP-2833.
