Subject [jira] [Updated] (HADOOP-8198) Support multiple network interfaces
Date Fri, 06 Apr 2012 00:06:26 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8198?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eli Collins updated HADOOP-8198:
--------------------------------

    Attachment: MultipleNifsv3.pdf

Updated design doc attached (v3).

- Based on feedback from Todd, Phil Zeyliger and Eric Sammer, I decided to skip the client-based
interface filtering altogether and start with server-side interface filter since we'll need
it eventually. Will update HDFS-3147.
- Updated discussion of exposing cluster-private interfaces to off-cluster clients (eg for
the pipeline)
- Based on feedback from Sanjay, better clarified the relationship between this work and using
host-level bonding

I'm going to create a branch for the HDFS-3140 work.

> 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.
