>                 Key: ACCUMULO-3938
>                 URL:
>             Project: Accumulo
>          Issue Type: Bug
>          Components: mapreduce, test
>            Reporter: Christopher Tubbs
>            Assignee: Christopher Tubbs
>             Fix For: 1.6.4, 1.7.1, 1.8.0
>          Time Spent: 0.5h
>  Remaining Estimate: 0h
> It looks like there's some places where we're incorrectly using getCanonicalName instead
of getName for serialization (when we expect to be able to later call Class.forName() to load
the class dynamically).
> Most of these occur in tests, and don't matter, because there's no difference between
the name and canonical name. However, there is a big issue in RangeInputSplit, which serializes
the AuthenticationToken name... this could be a serious bug if any other AuthenticationToken
types are created and used by people implementing their own security modules.
> General rule:
> * use getName() if you expect to later call forName()
> * use getCanonicalName() if you're generating code or printing log messages
