Subject Security Mechanisms in HDFS
Date Tue, 05 Jan 2010 15:44:14 GMT
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.
