Subject [jira] [Commented] (HADOOP-7509) Improve message when Authentication is required
Date Fri, 07 Oct 2011 20:06:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13123133#comment-13123133

Steve Loughran commented on HADOOP-7509:
----------------------------------------

This looks good, and I can see why no tests are needed.

One possible improvement -which I've started doing with connection errors -is have the exception
actually point to a hadoop wiki page entry where more detailed diagnostics and troubleshooting
hints can go in, such as for http://wiki.apache.org/hadoop/NoRouteToHost . Would that make
sense here -and is there already a wiki page to point to?

> The message when security is enabled and authentication is configured to be simple is
not explicit enough. It simply prints out "Authentication is required" and prints out a stack
trace. The message should be "Authorization (hadoop.security.authorization) is enabled but
authentication (hadoop.security.authentication) is configured as simple. Please configure
another method."
