    Labels: newbie  (was: newbie patch)

> Atomic add and remove of authorizations
> ---------------------------------------
>                 Key: ACCUMULO-1680
>                 URL:
>             Project: Accumulo
>          Issue Type: New Feature
>          Components: client, master, shell
>            Reporter: Chad Hardin
>            Priority: Minor
>              Labels: newbie
>             Fix For: 1.8.0
> 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.
