Hi, folks. Seeing from the changelog in version 0.22 that security related function is integrated in Hadoop to some extent, so I checked the source code from apache subversion repository and manage to get it working on my hosts. But during configuration and ordinary using, I feel nothing about the existence about security features added. So is there any document that describe how to use the security features ? If so, where can I find it? Many thanks, expecting your reply. Best regards
