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).
