[jira] [Updated] (MAPREDUCE-4594) Add init/shutdown methods to mapreduce Partitioner

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4594?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Radim Kolar updated MAPREDUCE-4594:
-----------------------------------

     Description: 
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.

The Partitioner and the RawComparator interfaces/extension points support only the Configurable API, which can be used for basic
