Mike Drob commented on ACCUMULO-421:
------------------------------------

Is this something that can be easily simulated with [HDFS Attributes|http://blog.cloudera.com/blog/2014/06/why-extended-attributes-are-coming-to-hdfs/]?

> To help support proper security in ACCUMULO-387, we should change the way Accumulo handles
file permissions in HDFS. Each table should have it's own group, and as we add/remove user
read access to the system, we should modify the group of the table accordingly. This way if
a user does a map reduce over the table files, the MR can only be run over files they can
read within Accumulo.
