-----------------------------------------------
Avner, as this is a new feature we should have the corresponding release notes.
Please let me know if you want me to take care of it. Thx

> Key: MAPREDUCE-4049
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4049
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: performance, task, tasktracker
> Affects Versions: 1.0.3, 1.1.0, 2.0.0-alpha, 3.0.0
> Reporter: Avner BenHanoch
> Assignee: Avner BenHanoch
> Labels: merge, plugin, rdma, shuffle
> Fix For: 2.0.3-alpha
>
> Attachments: HADOOP-1.x.y.patch, Hadoop Shuffle Plugin Design.rtf,
> MAPREDUCE-4049--branch-1.patch, mapreduce-4049.patch
>
>
> 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).

> # Hadoop Acceleration through Network Levitated Merging, by Prof. Weikuan Yu

> # I am attaching 2 documents with suggested Top Level Design for both plugins
> (currently, based on 1.0 branch)
> # I am providing link for downloading UDA - Mellanox's open source plugin
> that implements generic shuffle service using RDMA and levitated merge.
> Note: At this phase, the code is in C++ through JNI and you should consider
> it as beta only. Still, it can serve anyone that wants to implement or
> contribute to levitated merge. (Please be advised that levitated merge is
> mostly suit in very fast networks) -
