Pinned topic do data nodes need public IPs?

‏2013-01-22T17:30:40Z |
my understanding of the ideal reference architecture for hadoop is 1 management node with 3 data nodes, with all servers connected via their own switch for a private network, with multiple ports bonded for throughput.

data and tools still need to get in and out so one of the ports on the management node should be attached to the public intranet.

data nodes will send results through the management node as well as receive data from it, so they need no public intranet access (aside from IMM ports).

is this a correct understanding?

thanks,
mike

    Hi Mike,

    Correct, data nodes should communicate over a private network.

    Please see the diagram at this link:

    Thanks,
