Subject [jira] [Updated] (MAPREDUCE-4594) Add init/shutdown methods to mapreduce Partitioner
Date Fri, 23 Nov 2012 21:44:58 GMT

     [ 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.

  was:
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.

    Hadoop Flags:   (was: Incompatible change)
         Summary: Add init/shutdown methods to mapreduce Partitioner  (was: Add init/shutdown
methods to Partitioner and RawComparator)
