  <p>I am able to run sample programs given in hadoop-mapreduce-examples-2.0.0-cdh4.0.0.jar. 
  But I am getting this error when my job is submitted successfully to jobtracker . Looks like it is trying to access local file-system again (Although I have set all the required libraries for job execution in distributed cache still its trying to access local dir). Is this issues related to user privileges ? </p>

  --- No Result for following ----<br/></p>
  
  <pre><code>hdfs@Cloudera:/etc/hadoop/conf&gt; find . -name '**' | xargs grep "default.name"&lt;br/&gt;
  hdfs@Cloudera:/etc/hbase/conf&gt; find . -name '**' | xargs grep "default.name"&lt;br/&gt;
  </code></pre>
  
  <p>Instead I think with new APIS we are using -><br/>
  fs.defaultFS  --> hdfs://Cloudera:8020  which i have set properly<br/></p>
  
  <p>Although  for "fs.default.name" I got entries for hadoop cluster 0.20.2 (non-cloudera cluster)</p>
  
  <pre><code>cass-hadoop@Pratapgad:~/hadoop/conf&gt; find . -name '**' | xargs grep "default.name"&lt;br/&gt;
  ./core-default.xml:  &lt;name&gt;fs.default.name&lt;/name&gt;&lt;br/&gt;
  ./core-site.xml:  &lt;name&gt;fs.default.name&lt;/name&gt;&lt;br/&gt;
  </code></pre>
  
  <p>I think cdh4 default configuration should add this entry in respective directory. (If its bug).</p>
  
  <p>The command I am using to run my progrmme -<br/></p>
