Subject [jira] [Commented] (HADOOP-7307) Remove Dr Who references
Date Tue, 24 May 2011 03:09:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13038365#comment-13038365

Allen Wittenauer commented on HADOOP-7307:

Hmm. That's sort of surprising.  I would have expected the user name to get resolved to the
user that is running the datanode when the built-in auth was being used.  (Doesn't it default
to the username of the user running the Java process everywhere else?  Why would it be different
for the HDFS web ui?)  But that's also bad for what are hopefully obvious reasons though.

FWIW, in Apache 0.20.2 and prior, we had dfs.web.ugi which looks like it defaulted to "webuser,webugi".

I'm inclined to think that we likely need to bring this setting back and default it to either
webuser or DrWho.  It sounds like the default changed in 0.21, so this is a tricky one.

> I've had feedback from a number of different operators that the "dr who" references that
occasionally come out of Hadoop are annoying and confusing. We should replace them with more
descriptive error messages, usernames, etc.
