Luke Lu commented on MAPREDUCE-4594:
------------------------------------

# Fix test name and comments. It's neither TestMapTask nor TestCounters. 
Suggestion: TestPartitionerSetupCleanup
# Make TestingPartitioner as a static inner class of the test.
# Indentation should be two spaces. No tabs.
                
> Add init/shutdown methods to mapreduce Partitioner

> The Partitioner supports only the Configurable API, which can be used for 
> basic init in setConf(). Problem is that there is no shutdown function.
> I propose to use standard setup() cleanup() functions like in mapper / 
> reducer.
> Use case is that I need to start and stop spring context and datagrid client.
