> 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.
