Chad Hardin created ACCUMULO-1680:
-------------------------------------

             Summary: Atomic add and remove of authorizations
                 Key: ACCUMULO-1680
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1680
             Project: Accumulo
          Issue Type: New Feature
          Components: client, master, shell
    Affects Versions: 1.6.0
            Reporter: Chad Hardin
            Priority: Minor
             Fix For: 1.6.0


Currently, adding and removing an auth presents a race condition because of the two separate
calls required to get, modify, then set the authorizations for a user.  

Instead, it should be possible to add or remove one or more auths without there being a race
condition.

I also propose adding two new commands to the shell to expose this functionality.  

It appears to be that this is not a difficult feature to add, by making use of  ZooReaderWriter.mutate()
in the FATE packages.  I think the bulk of the work will be in changing the various interfaces
(shell and programmatically) to expose this functionality.

I would like to do this work and I'm a accumulo newbie, so any guidance would be appreciated.
