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). > References: > # Hadoop Acceleration through Network Levitated Merging, by Prof. Weikuan Yu > from Auburn 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) -- This message is automatically generated by JIRA.
