Edward J. Yoon commented on HAMA-376:
-------------------------------------

>> refactored version allows to pass customized directives by extending Directive class;
and the customized directive will be processed with corresponded handler.

+1 but this patch did not contain DirectiveHandler class.

> The current Hama BSPMaster and GroomServer make use of dispatch() and report() function
for communication. But the directives passed in is composite, which is a bit difficult to
customize new directives for future use. The refactored version allows to pass customized
directives by extending Directive class; and the customized directive will be processed with
corresponded handler. Also, directives are put into queue, so the rpc method e.g. dispatch()
do not need to go through the whole method until the execution is finished.
