Subject [jira] Commented: (HADOOP-6210) Bind Hadoop RPC outgoing to a specific nic
Date Tue, 07 Sep 2010 22:31:35 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6210?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12907000#action_12907000
] 

Allen Wittenauer commented on HADOOP-6210:
------------------------------------------

No, no, it is actually better to bind to a specific IP address.

I just mention that I was thinking of nic aliases when I wrote that because most of the non-hacky
HA solutions I'm aware of use real, functional aliases to perform the ip movement from machine
to machine.

> In environments with multiple interfaces on a machine, it would be useful to be able
to bind outgoing traffic to specific interfaces rather than letting the outbound be picked
at random.  This is especially important for things like Solaris IPMP.
