Laxman commented on MAPREDUCE-4049:
-----------------------------------
bq. You are warmly welcomed to contribute to push the algorithms of this plugin
to the core of vanilla Hadoop
Thank you Avner. I wish to see this as part of hadoop.
I'm not able to build UDA you have provided as per BUILD.README provided in the
downloaded bundle. SVN repository provided is not accessible/resolvable.

bq. as well as to help accepting my straight forward patch in this JIRA issue.
I will personally request few of my friends (Hadoop contributors) to review
this jira.

> 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
> Labels: merge, plugin, rdma, shuffle
> Fix For: trunk
>
> Attachments: HADOOP-1.x.y.patch, Hadoop Shuffle Plugin Design.rtf,

> 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).

> # 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) -
