---------------------------------------
Would need to consider table cloning.
> Table ACLs should be reflected in HDFS Table directories

> Key: ACCUMULO-421
> URL: https://issues.apache.org/jira/browse/ACCUMULO-421
> Project: Accumulo
> Issue Type: Improvement
> Reporter: John Vines
> Fix For: 1.5.0
>
>
> 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.
