[jira] [Created] (ACCUMULO-421) Table ACLs should be reflected in
HDFS Table directories
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.

Would need to consider table cloning.

---------------------------------------
May not want each table to have its own group, this would imply that Accumulo is creating groups automatically in HDFS. It may be more desirable to let users associate a table with an HDFS group?
