Subject [jira] [Created] (ACCUMULO-3375) Move user and permission data into a table

             Summary: Move user and permission data into a table
                 Key: ACCUMULO-3375
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3375
             Project: Accumulo
          Issue Type: Improvement
            Reporter: Josh Elser


We currently use ZooKeeper to store the user database (name and password) in addition to the
authorizations and permissions for each user.

ZooKeeper is designed for distributed configuration and synchronization/coordination tasks;
it is not designed to be a persistent store. In this case it would be better to use a table
to manage this information.

I think this might reduce some complexity in managing that database, notably better recovery
if ZK dies for some reason. Having a table might trivialize import/export of the user database
(ACCUMULO-1722 is what made me think of this).
