Rajiv Chittajallu commented on MAPREDUCE-4168:
----------------------------------------------
Trying to understand actual need for multihomed systems. With all popular
specialty networks and standard ethernet support IP, which could be used for
management and application traffic, it seems unnecessary to make current stack
handle multiple addresses.
1. Bandwidth - 10G is commodity. If this is not sufficient, L2 trunks is an
simpler solution (If your vendor doesn't support LACP, probably should consider
alternative, its pretty standard now). Cabling and port density requirements
would be same.
2. Client and cluster networks are in different subnets: routing?
> Support multiple network interfaces
