I've downloaded hadoop from Yahoo tutorial, started linux VM with hadoop and in eclipse created new DFS location (entered IP of my VM, Map/Reduce master port 9001, DFS port 9000. But in the node I got the error "Error:null."

enter image description here

What I'm doing wrong?

I'm using Eclipse Europe 3.3.1 and Hadoop 0.18.0.

Thanks for helping.

  • There is a newer version of Hadoop plugin at at https://code.google.com/p/hadoop-eclipse-plugin/downloads/list – blue-sky Mar 04 '13 at 09:11
  • Try to set up hadoop on your local instead of using a VM. That way you will be able to configure eclipse easily. – Anutosh Datta Mar 04 '13 at 13:58

You should check the additional properties that you are able to configure. I was also getting this problem but the actual problem was that hadoop.job.ugi property was not available to be setup.To fix this, go to "\workspace\.metadata\.plugins\org.apache.hadoop.eclipse\locations". Here open the XML file and just add the property "hadoop.job.ugi" with value "hadoop-user,ABC" and then restart your eclipse. It worked for me.

I've configured properly eclipse when had installed it in my VM where hadoop was. But due to incompatible new versions of eclipse and eclipse hadoop plugin I refused to use it, because seems to me that using this plugin doesn't have any good benefits.

I was facing the same problem, i thinks the problem because there is no folder or files in the HDFS,i solved with these steps:

  • hadoop dfs -mkdir /name of folder

  • hadoop fs -ls /
