Subject [jira] [Resolved] (MAPREDUCE-4049) plugin for generic shuffle service
Date Tue, 11 Dec 2012 14:29:27 GMT

Alejandro Abdelnur resolved MAPREDUCE-4049.
-------------------------------------------

    Resolution: Fixed

Chris thanks for taking a look at these JIRAs.

Withdrawing my -1. I'm OK with doing necessary tweaks in follow up JIRAs.

I'd suggest we merge MAPREDUCE-4809 and MAPREDUCE-4807 to trunk. Then we can do the incremental
work for MAPREDUCE-4812 and MAPREDUCE-4808 in trunk as well.

Arun, is that OK with you?

> 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).

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)
> # 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) - [http://www.mellanox.com/content/pages.php?pg=products_dyn&product_family=144&menu_section=69]
