Subject [jira] [Commented] (CRUNCH-185) Make the MemPipeline#done return a PipelineResult with the Counters inside.

Christian Tzolov commented on CRUNCH-185:
-----------------------------------------

@Josh I am not sure I see the value of the MemPipeline. It looks to me like is a stub/mock
class without practical value beyond the testing.

> The MRPipeline exposes the job counters via the PipelineResult. The MemPipeline behaves
differently. It always returns an EMPTY PipelineResult and exposes a static getCounters()
method. 
> To make both implementations behave alike the MemPipeline should return a single-staged
PipelineResult containing the Counters. 
> Also the MemPipeline should provide a mechanism to reset the Counters. At the moment
there is no other mechanism to reset but restarting the application.
