                 URL: https://issues.apache.org/jira/browse/HADOOP-8198
             Project: Hadoop Common
          Issue Type: New Feature
          Components: io, performance
            Reporter: Eli Collins
            Assignee: Eli Collins


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.
