Date Wed, 19 Oct 2011 09:50:11 GMT
Fetch failures if used ephemeral port for property "mapreduce.shuffle.port". 

                 Key: MAPREDUCE-3211
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3211
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: job submission, mrv2
    Affects Versions: 0.24.0
         Environment: Linux
            Reporter: Prashant Sharma
            Assignee: Prashant Sharma
             Fix For: 0.24.0

To reproduce the bug. 

Use the following property in mapred-site.xml

      <name> mapreduce.framework.name</name>
      <name> mapreduce.shuffle.port</name>

and following in yarn-site.xml

    <description>shuffle service that needs to be set for Map Reduce to run </description>


Then try to start the yarn daemons.

And submit the job. (which would eventually fail).

Also observe NM logs. It says shuffle handler service started at port 0; :P
