-----------------------------------
I try to patch the HADOOP-8468-total.patch to the release fro site
http://svn.apache.org/repos/asf/hadoop/common/tags/release-2.0.2-alpha/,but
failed!Cloud anyone give me some suggestion?The errors are as follow:

> Umbrella of enhancements to support different failure and locality topologies
> -----------------------------------------------------------------------------
>
> Key: HADOOP-8468
> URL: https://issues.apache.org/jira/browse/HADOOP-8468
> Project: Hadoop Common
> Issue Type: Improvement
> Components: ha, io
> Affects Versions: 1.0.0, 2.0.0-alpha
> Reporter: Junping Du
> Assignee: Junping Du
> Attachments: HADOOP-8468-total.patch, HADOOP-8468-total-v3.patch,
> HVE_Hadoop World Meetup 2012.pptx, HVE User Guide on branch-1(draft ).pdf,
> Proposal for enchanced failure and locality topologies.pdf, Proposal for
> enchanced failure and locality topologies (revised-1.0).pdf
>
>
> The current hadoop network topology (described in some previous issues like:
> Hadoop-692) works well in classic three-tiers network when it comes out.
> However, it does not take into account other failure models or changes in the
> infrastructure that can affect network bandwidth efficiency like:
> virtualization.
> Virtualized platform has following genes that shouldn't been ignored by
> hadoop topology in scheduling tasks, placing replica, do balancing or
> fetching block for reading:
> 1. VMs on the same physical host are affected by the same hardware failure.
> In order to match the reliability of a physical deployment, replication of
> data across two virtual machines on the same host should be avoided.
> 2. The network between VMs on the same physical host has higher throughput
> and lower latency and does not consume any physical switch bandwidth.
> Thus, we propose to make hadoop network topology extend-able and introduce a
> new level in the hierarchical topology, a node group level, which maps well
> onto an infrastructure that is based on a virtualized environment.
