---------------------------------------

    Attachment: HADOOP-1.x.y.patch

Hi Arun,
- The attached patch, addresses your comments about: TaskTracker.MapOutputServlet to implement ShuffleProvider interface, spelling, and mapred-default.xml.
- Next week, I'll submit patch that will add tests.
- Immediately after that, I'll work on patch for the trunk, based on the due-diligence I did.
 
Cheers,
 Avner

> Support generic shuffle service as set of two plugins: ShuffleProvider & ShuffleConsumer.
> This will satisfy the following needs:
> # Better shuffle and merge performance. For example: we are working on shuffle plugin that performs shuffle over RDMA in fast networks (10gE, 40gE, or Infiniband) instead of using the current HTTP shuffle. Based on the fast RDMA shuffle, the plugin can also utilize a suitable merge approach during the intermediate merges. Hence, getting much better performance.
> # Satisfy MAPREDUCE-3060 - generic shuffle service for avoiding hidden dependency of NodeManager with a specific version of mapreduce shuffle (currently targeted to 0.24.0).
> References:
> # Hadoop Acceleration through Network Levitated Merging, by Prof. Weikuan Yu from Auburn University with others, [http://pasl.eng.auburn.edu/pubs/sc11-netlev.pdf]
> # I am attaching 2 documents with suggested Top Level Design for both plugins (currently, based on 1.0 branch)
