Josh Elser commented on ACCUMULO-2877:
--------------------------------------

bq. If the client API does not call CachedConfiguration, then the method is not 
necessary. We could re-open ACCUMULO-43.

Would it make sense for public API methods that interact directly with HDFS 
({{TableOperationsImpl#importDirectory}}) to accept a Configuration object? We 
could add that support moving forward, deprecate the version that relies on 
CachedConfiguration, and then have a clear time when we can remove 
CachedConfiguration. It looks like OfflineScanner could also benefit from the 
same approach (although we could create a Configuration with the relevant 
information from accumulo-site.xml too).

> The method {{CachedConfiguration.setInstance()}} is a public static method 
> but is never used outside the class. It should be hidden or removed.
