Subject [jira] [Updated] (MAPREDUCE-4049) plugin for generic shuffle service
Date Wed, 21 Mar 2012 12:47:39 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4049?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Avner BenHanoch updated MAPREDUCE-4049:
---------------------------------------

         Description: 
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 will soon attach document with suggested API for the plugin
