Thanks . 
Each host has 8gb but hadoop is estimating too much space the number estimated is too big
for any host in the world ;). My input data are  simple text files that do not exceed 20
mb. I do not know why hadooop os estimating that much.

It is possible that the hosts which are running tasks are do not have enough space. Those
dirs are confiugred in mapred-site.xml

Subject: About running a simple wordcount mapreduce
To: mapreduce-issues@hadoop.apache.org

I am trying to run  a wordcount mapreduce job on several files (<20 mb) using two machines
. I get stuck on 0% map 0% reduce.
The jobtracker log file shows the following warning:
 WARN org.apache.hadoop.mapred.JobInProgress: No room for map task. Node hadoop0.novalocal
has 8791384064 bytes free; but we expect map to take 1317624576693539401

Please help me ,
Best Regards,
