Do you have the JT and NN on the same node?
Look here on the Lars Francke´s post:
http://gbif.blogspot.com/2011/01/setting-up-hadoop-cluster-part-1-manual.html
This is a very schema how to install Hadoop, and look the configuration
that he used for the name and data directories.
If this directories are in the same disk, and you don´t have enough
space for it, you can find that exception.
My recomendation is to divide these directories in separate discs with a
very similar schema to the Lars´s configuration
Another recomendation is to check the Hadoop´s logs. Read about this here:

Hi,
I encounter a problem as following:
Error - Job initialization failed:
org.apache.hadoop.fs.FSError: java.io.IOException: No space left on device

......
So, I think that the HDFS is full or something, but I cannot find a way to
address the problem, if you had some suggestion, Please show me , thank you.
Best Regards
