Subject [jira] [Created] (MAPREDUCE-4049) plugin for generic shuffle service
Date Wed, 21 Mar 2012 12:19:39 GMT
plugin for generic shuffle service
----------------------------------

                 Key: MAPREDUCE-4049
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4049
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: performance, task, tasktracker
    Affects Versions: 1.0.1, 0.23.1
            Reporter: Avner BenHanoch


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 (Mellanox with Prof. Weikuan Yu from
Auburn University) 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).
