Subject [jira] [Commented] (HADOOP-10301) AuthenticationFilter should return Forbidden for failed authentication
Date Wed, 05 Feb 2014 21:38:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13892599#comment-13892599
] 

Alejandro Abdelnur commented on HADOOP-10301:
---------------------------------------------

[~daryn], I may be missing something but it seems that we can still return a 401 without the
WWW-Authenticate header right?

Shouldn't we define instead?

{code}
    int errCode = HttpServletResponse.SC_NOT_ACCEPTABLE
{code}

> The hadoop-auth AuthenticationFilter returns a 401 Unauthorized without a WWW-Authenticate
headers.  The is illegal per the HTTP RPC and causes a NPE in the HttpUrlConnection.
> This is half of a fix that affects webhdfs.  See HDFS-4564.
