Subject Re: hadoop current properties
Date Fri, 30 Nov 2012 04:03:31 GMT
It is coming from the default properties file - mapred-default.xml. The
order of loading configuration in Hadoop is default.xml > site.xml >
job.xml.

<property>
  <name>mapred.task.tracker.report.address</name>
  <value>127.0.0.1:0</value>
  <description>The interface and port that task tracker server listens on.
  Since it is only connected to by the tasks, it uses the local interface.
  EXPERT ONLY. Should only be changed if your host does not have the
loopback
  interface.</description>
</property>

>From the description, I feel it should not cause any broken links for you.
Can you tell us which links are broken ?

Thanks
