Hi list, Could any hadoop gurus tell me what kinds of security mechanisms are already(or planed to be) implemented in hadoop filesystem?
I know there're some kind of Linux-like 9 bits(ie. ower,group,other) access control existing in hdfs. Unfortunately there're no user authentication modules. Seems like a big defect for hdfs since without authentication, user authorization makes little sense. It has mentioned in the official HDFS docs that another Kerberos authentication module will be added to HDFS in the future. Could anybody tell me when this will happen? And i'm just curious is there any other security mechanisms already implemented in hdfs in addition to those i mentioned above... pls help, thanks a lot. -- Regards Xi Yu (禹熹) Jonathan Swift<http://www.brainyquote.com/quotes/authors/j/jonathan_swift.html> - "May you live every day of your life."
