Eli Collins commented on HADOOP-8198:
-------------------------------------
I should clarify that host-level bonding works today as long as the IP of bond
is where IPC comes from as well, eg if a DN is configured only to listen on the
IP of the bond. It breaks if the DN listens on all interfaces and does IPC to
the NN on an interface that's not the bond. Check out specifics in HDFS-3146.
> Support multiple network interfaces

> 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.
