Hadoop does not currently utilize multiple network interfaces, which is a common user request,
and important in enterprise environments. This jira covers a proposal for enhancements to
Hadoop so it better utilizes multiple network interfaces. The primary motivation being improved
performance, performance isolation, resource utilization and fault tolerance. The attached
design doc covers the high-level use cases, requirements, a proposal for trunk/0.23, discussion
on related features, and a proposal for Hadoop 1.x that covers a subset of the functionality
of the trunk/0.23 proposal.
