Bill Havanki updated ACCUMULO-2497:
-----------------------------------
Description:
Working on ACCUMULO-2470 (unit tests for server/base) is made difficult by the
heavy dependence on static method calls in our architecture. This ticket is for
introducing an {{InstanceFactory}} interface that will greatly ease testing of
code that currently retrieves instances via static methods (e.g.,
{{HdfsZooInstance.getInstance()}}).
Limitations:
* Work here should be limited to creating {{InstanceFactory}} and its
implementations, and not integrating it into existing code (yet).
* Work is limited to 1.6 and later. To avoid perturbing the 1.6.0 release no
new code may be introduced into the public API ({{Instance}} is in the public
API).
* A refactoring of the client API is being considered (see ACCUMULO-2128), so
this change should not further complicate - and should hopefully help - that
future effort.
