Description

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.
