Subject [jira] [Resolved] (MAPREDUCE-2590) How to access Job Configuration file in Partitioner

Harsh J resolved MAPREDUCE-2590.
--------------------------------

    Resolution: Invalid

Somnath,

Thank you for taking time to file an issue!

MAPREDUCE-2474 added a API doc that specifies how to make your Partitioners configurable (API
doc is clear on how to do so as well). You don't need to apply the patch, since its a docfix
improvement.

However, you can find a detailed, example-ized solution here: http://cornercases.wordpress.com/2011/05/06/an-example-configurable-partitioner/

Resolving as Invalid (covered by MAPREDUCE-2474).

> I need to access Job Configuration file in partitioner to fetch some information. Generally
we can access job configuration file easily in map or reduce side by this code 
> Configuration config = context.getConfiguration();
> But this same code cannot be used in partitioner. To solve this issue I followed the
patch https://issues.apache.org/jira/browse/MAPREDUCE-2474 but it is a doc so I downloaded
the latest trunk code and generate the jar but I did not get any extra feature from that to
call the job configuration file So any one knows the code to call Job Configuration file in
partitioner.
