Christopher Tubbs resolved ACCUMULO-2415.
-----------------------------------------
Resolution: Not A Problem
In spite of the javadoc, it actually throws TableNotFoundException instead.
> Refactor Tables.getNamespaceId to not throw IllegalArgumentException

> Key: ACCUMULO-2415

> Project: Accumulo
> Issue Type: Improvement
> Reporter: Christopher Tubbs
> Priority: Minor
>
> ACCUMULO-2087 introduced throwing IllegalArgumentException if a table does
> not exist when looking up it's namespace. This caused bug ACCUMULO-2393,
> which handles that case.
> However, this implementation is very brittle, because it relies on a runtime
> exception, which could hide other errors. It's also throwing an
> IllegalArgumentException when really, the argument is perfectly valid.
> This code should be refactored to handle these circumstances better, in a way
> that doesn't hide potential bugs. Because this is internal implementation
> details and a utility method, and not public API, we have some flexibility
> here, but we need to ensure we have the correct behavior for every caller
> that uses this method.
