             Summary: Introduce a KeyBuilder classc
                 Key: ACCUMULO-4376
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4376
             Project: Accumulo
          Issue Type: Improvement
          Components: client
            Reporter: Josh Elser
             Fix For: 1.9.0


In looking at ACCUMULO-4375, I was a little frustrated at how we have 3x 
constructors than Key really provides just to support {{byte[]}}, {{Text}}, and 
{{CharSequence}} arguments. Additionally, the {{copy}} argument forces the user 
to use the most specific (most arguments) constructor if they want to avoid the 
copy. This makes constructing a Key from just a row while avoiding a copy very 
pedantic.

I think a KeyBuilder (or KeyFactory) class would be a big usability benefit and 
reduce the amount of code that clients have to write to most efficiently 
construct Keys.
