----------------------------------------
ticket edited, to be for partiotioner only since it is class and not interface,
easy to change.
> Add init/shutdown methods to mapreduce Partitioner
> --------------------------------------------------
>
> Key: MAPREDUCE-4594
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4594
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: client
> Affects Versions: trunk
> Reporter: Radim Kolar
>
> 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.
