title: Hadoop with eclipse is not connecting
body: <p>I am using ubuntu 12.04. I am trying to connect hadoop in eclipse.Successfully installed plugin for 1.04. I am using java 1.7 for this.</p>
  
  <p>My configuration data are 
                           username:hduser,locationname:test,map/reduce host port are localhost:9101 and M/R masterhost localhost:9100.</p>
  
  <p>My temp directory is /app/hduser/temp.
  As per this location I set advanced parameters.But I was not able to set fs.s3.buffer.dir as there was no such directory created like /app/hadoop/tmp//s3. unable to set map reduce master directory.I only found local directory. I didnot find mapred.jobtracker.persist.job.dir. And also map red temp dir.</p>
  
  <p>When I ran hadoop in pseudo distributed mode I didnot found any datanode running also with JPS.</p>
  
  <p>I am  not sure what is the problem here.In eclipse I got the error while setting the dfs server.I got the message like...</p>
  
  <p>An internal error occurred during: "Connecting to DFS test".
