Subject [jira] [Commented] (HADOOP-8198) Support multiple network interfaces
Date Mon, 09 Apr 2012 16:59:19 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13249963#comment-13249963

Sanjay Radia commented on HADOOP-8198:
--------------------------------------

> .. host-level bonding works today as long as the IP of bond is where IPC comes from as
well ...
Hence if Hadoop is correctly configured then multiple NICs work for use case 1.
Eli, how important is use case 2 for Hadoop users? 
One of my concerns is that this code change is going to have some tricky corner cases to get
right based on experience with the recent ipAddress-dnsName change patch (forget jira number)
that resulted in some subtle bugs down the road with tokens etc.

> 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.
