Subject [jira] [Updated] (HADOOP-6616) Improve documentation for rack awareness
Date Thu, 11 Oct 2012 07:33:05 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6616?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Adam Faris updated HADOOP-6616:
-------------------------------

    Attachment: hadoop-6616.patch.3

Sorry for the delay but wanted to rethink the examples to explain how this works.  I updated
the bash script to show how simple topology scripts could be.  I removed the perl example
as both the perl and bash script were doing the same thing of splitting the IP on dots.  Finally
the python script has been updated to print the network instead of relying on matching host
names in a contrived example.

-- Thanks, Adam

> The current documentation for rack awareness (http://hadoop.apache.org/common/docs/r0.20.0/cluster_setup.html#Hadoop+Rack+Awareness)
should be augmented to include a sample script.
