> 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.
