[jira] Commented: (HADOOP-3854) org.apache.hadoop.http.HttpServer
should support user configurable filter
[ https://issues.apache.org/jira/browse/HADOOP-3854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12619729#action_12619729 ]
Doug Cutting commented on HADOOP-3854:
--------------------------------------
I'm trying to think of use cases for this. Logging and authentication are core functionalities of Hadoop, that folks shouldn't be replacing in this way, no? We should consistently log using a logging API, and provide ways for folks to replace that. Similarly for authentication: we should provide an extensible authentication API that folks can replace. Both logging and authentication are done in other places besides from HTTP servers. I can see this as a nice internal API, as a way to call the standard logging and authentication APIs, but, once we've done that, do we want to support users overriding that and specifying different logging and authentication mechanisms, just for the HTTP services, and not for the RPC and raw socket interfaces? That sounds error-prone. Or am I missing something?

> 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.
