Subject [jira] Commented: (HADOOP-3854) org.apache.hadoop.http.HttpServer should support user configurable filter
Date Mon, 04 Aug 2008 23:36:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12619743#action_12619743
] 

Doug Cutting commented on HADOOP-3854:
--------------------------------------

I agree that authentication and logging on our web servers needs to be extensible.  I am also
aware that filters support universal functions.  What I question is whether we want to support
authentication and logging extensibility with such a universal function, or whether it might
be better to provide more specific extensibility mechanisms for these cases.  Should we perhaps
instead have one filter we call to authenticate requests, and another to log them, that folks
can separately replace?  In the authentication case, should we support a standard mechanism
of annotating the http request with the user's credentials?  Or do you think for some reason
those would be overkill, that the more-general mechanism is more appropriate here?

I don't necessarily think this is a bad approach, I'm just trying to better understand its
motivation.

> Filters provide universal functions such as authentication, logging and auditing, etc.
 HttpServer should support configurable filters, so that individual site administrators could
possibly configure filters for their web site.
