             Summary: Add API method(s) that support fetching currently assigned locations
for tablets
                 Key: ACCUMULO-2883
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2883
             Project: Accumulo
          Issue Type: Sub-task
          Components: client
            Reporter: Josh Elser


TabletLocator already exists, but isn't officially a part of the "public API" and is clunky
for users to invoke. In trying to co-locate external processes with the tabletservers that
are hosting some data, it would be nice to have some means that users can invoke that will
return them these assignments.

Memory concerns are an issue for tables with many splits (e.g. avoiding creating a Set of
100k tablet locations for a table), but we also want to provide the ability to ask pointed
questions. Likely building something that accepts a Range (or Collection<Range>) would
be best.
