Radim Kolar commented on MAPREDUCE-4594:
----------------------------------------
What about to convert RawComparator from interface to class?
> Add init/shutdown methods to Partitioner and RawComparator
> ----------------------------------------------------------
>
> 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 and the RawComparator interfaces/extension points support
> 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.
