My hadoop is running perfectly well , I am using hadoop-0.20.2.

Try adding _Djava.io.tmpdir= to your java options.
I found this in the error log output of my mapreduce job when it failed due to this directory running out of space.

A couple of links you may find interesting to read:
- http://bugs.sun.com/view_bug.do?bug_id=6447182
- java hsperfdata directory
- https://issues.apache.org/jira/browse/HADOOP-6284
From looking through those pages, this is a java thing (storage of performance counters), which may or may not be easily configurable for another location. Is your /tmp directory full or relativey small?
Can you run a df -h from your command line, and see how much space is assigned to that partition, and dig into /tmp to discover what else might be consuming the space.
I'm surprised that your OS and other application are not adversely affected by the lack of temporary storage space.
