AccumuloInputFormat getters

[Josh Elser]

Why are all of the getters on the AccumuloInputFormat protected (really, 
InputFormatBase) instead of public?

This has repeatedly infuriated me as it makes it impossible for me to 
verify that the Configuration actually has the data in it as needed.

It seems intentional so I figured I would ask before making a ticket and 
changing it.
